Turk, so 30" draw at 70lbs with a peep and loop on the string. You shoot the Maxima Hunter KV 350 with 100gr heads cut to 30" correct? If so, that arrow is to weak. If you went to the regular Maxima Hunter 450 you would be really close. Might have to cut a 1/4" off the shaft to be perfect though, just have to experiment and see.
So you say that a Maximum 450 cut to 30" or 29.75" would almost be perfect? Is this ran through a program or what you think, (I am not trying to come off as rude I am just curious)?

1- My draw is 30" and so I had them cut to 30." This gives me about 2-2.5" of arrow past my rest.
2- I hunt big game and wanted weight on my arrow. an extra inch or two does that.
Sooo...You are saying if I cut the 350's to 28" at a 30" draw that should put me much closer to perfect spine? Is this your opinion or something ran through a software program, (again please don't take it the wrong way, I am just trying to learn and understand your thought process)?

Its out of a program that I find to be very close with my bows and it shows your present set up not even close to borderline. Let me ask you this, when you have your bow dialed in to shoot fieldpoints and then you switch to broadheads, which way do you move the rest? Cutting 2" is still going to be to weak but it would be an improvement.

My arrows are that long for really only two reasons.
1- My draw is 30" and so I had them cut to 30." This gives me about 2-2.5" of arrow past my rest.
Don't worry about if the arrow is sticking out past the rest. It isn't important unless you are shooting a bow where you hand may come in contact with the broadhead, like a traditional bow.
2- I hunt big game and wanted weight on my arrow. an extra inch or two does that.
Two inches of carbon arrow isn't going to matter one way or the other. It's only about 17 grains total. However, an arrow with the proper spine will give you better penetration because it will not be wasting energy correcting its flight on the way to the target. Once it gets there it will hit the animal straight on instead of at a slight angle and the arrow will penetrate in a straight line instead of slapping the sides of the hole as the arrow passes through.

An good example is my own set up. I have an Invasion set at 71 pounds and 29.5" draw length. My arrows (Easton ACC 3-71's) were initially cut to 29 inches. Broadhead flight was only decent and no matter how much fine tuning I did the broadhead tipped arrows just weren't getting it. I had cut them that length with out running though OT2 knowing I could go shorter if I needed to. After dicking around with tuning for a couple of days I ran my numbers through OT2 and the perfect spine for my set up was actually 27.5" with a 100 grain tip. Once I cut the arrows everything came together and broadhead flight was perfect as far as I cared to shoot (70 yards) at a target.

Cutting 2" is still going to be to weak but it would be an improvement.
So in your program what length of an arrow (say the Maxium Hunter dual spine weight forward 450's) should I be shooting?
Does your software show an optimum arrow cut to 'x' length that would be the best spinned for my setup?
Two questions (again I apprecite all your insight, I am just trying to learn from this):
1- Does 1" of draw really cause this much change in spine? My cousin shoots 29" and has his arrows cut to 29" (same as mine) and he has zero issues?
2- How come their charts and another software program (I had asked on this forum, I will try and dig up the advice I received a while back) show that I should be fine?

This comes from years of experience and using software when I need to. Cutting the 2 inches will likely still not give you the perfect spine but it will be much closer than were you are now. If you can fork out the cash the 450's is where you really need to go.
An good example is my own set up. I have an Invasion set at 71 pounds and 29.5" draw length. My arrows (Easton ACC 3-71's) were initially cut to 29 inches.

---I know I am asking you the same questions as screamin, I really am just looking for more opinions from those with more knowledge on the subject than I.

Is your cousin shooting the exact same bow with the exact same draw weight?
But right off the bat his arrows are 1" shorter and his draw length is 1" shorter. Both of these contribute to needing a less stiff arrow. If he is shooting a different bow with a different cam this would also effect the arrow needed.
2- How come their charts and another software program (I had asked on this forum, I will try and dig up the advice I received a while back) show that I should be fine?

bb-
Very enlightening! Thank you for taking the time to comment on my posts, I appreciate it.
Hopefully someone who has the program could run my numbers and see just what size shaft arrow (and which arrow) would work out best for my current set up?

Bulls I no longer have OT2. I just prefer using archers advantage. Much more user friendly. However I think you have this one covered.
My AA program is on my wifes laptop and she is studying for 5 test this week so im on my phone for a while.

Broadheads hitting right of field points IS a weak arrow reaction.
Easy to check. Back poundage off 5#. See if it gets better. If it does. You know you need lower poundage, stiffer arrows or shorter arrows.
