Just keep that #%^! dead horse out of MY lane, Frank!
As long as whatever weight arrow and whatever broadhead you use consistenly gives you accurate shots, clean kills, good blood trails and you don' t mind the work to keep it up and running right, then use it. It' s when you' re having problems with making accurate shots, getting a decent bow tune, getting poor penetration or are losing animals because of bad trails (or bad tracking skills) something has to change.
For me, I' m more skilled at judging yardage than I am at tuning a bow. My draw length is very long and I MUST have a very consistent arrow and near perfect form to shoot accurately. Heavy aluminum arrows have proven themselves to tune much easier and shoot much better FOR ME, with broadheads and in all circumstances, so that' s what I use. My carbon arrows... I can only shoot them with field points because they go nuts even with low profile broadheads. Since I' m still old fashioned enough to not trust mechanicals, those arrows are consigned exclusively to the 3D course.
At 60 pounds draw weight, even the carbon arrows I' ve tried are nearly 8 grains per pound. At 70 pounds, they' re nearly 7 gpp. Even though that' s as light as I can go with today' s arrow materials, I still call that a moderate weight arrow. Some folks think they' re heavy. My point of view is an arrow isn' t heavy until it gets over 9 grains per pound. My favorite hunting arrows run 10-11 grains per pound.
What gets my hackles raised is when someone starts saying that light and fast is the ONLY way to go. I don' t remember who it was, but someone on this forum once said that if you aren' t shooting around 275 fps, then you' re UNETHICAL!![>:] No. What' s unethical is trying to attain a certain arrow speed, in order to keep up with the Joneses, at the expense of being able to control that speed in hunting situations.
I' ve been around this bowhunting stuff long enough to know my limitations and I' ve found what works for me. I' ve tried all the new stuff, but I keep going back to my old standby equipment. I ENJOY the old style stuff. I shoot it VERY well. That' s enough for me.
