Im looking for a pretty large diameter light arrow (duh). A guy i shoot with who used to shoot clx250's showed me some new arrows he got the other day. they are victory X-ringer HV350's. they are 6.8gpi and .372 in diameter. They are lighter and bigger than the cxl250. My question is would they be the right spine for my "new" bow. 60#captain 29"draw. Also what size tip should i shoot. i was thinking a 100grain tip but i honestly dont know too much about arrows. i feel very ignorant about arrow spine etc... soeducate meguys. would this arrow setup be good for 3d/indoors.

The Easton Fatboy shafts would also be good "linecutter" arrows. You want a 200/250 in the CE shafts, or a 400 series Easton shaft. At 28 or 29 inches, 60 lb. draw, and with a 100 grain tip; the 400 series shafts will spine out just about perfect. 340's and 350's are going to be too stiff - unless you want to run a 31" shaft and possibly go with a 125 grain tip.

Are u saying the 340-350 eastons will be too stiff?

Roskoe

Yes. They are about perfect for 70 lb. bow, when you use normal (28/29) length arrows with regular 100 gr. tips. But when you drop to 60 lbs, the 400 series (200/250 for CE) are the ones you want.

btw, the fatboy 400 is 7.8gpi compared to the 6.8 gpi in the xringer350. would the

spine better for my setup. i feel kinda helpless here guys lol! i feel like the whole arrow spine thing is what im most ignorant about in archery.

What are using this arrow for? I'm kinda confused by the title....3d indoor shooting? Or indoorspot shooting at 20 yds?

The GPI of the arrow has nothing to do with spine. It is simply an indication of the physical weight of the shaft. The spine is a stiffness quantification. How much the arrow bends when a 1.94 lb. weight is hung from the middle. If it bends .34"; it is a 340 shaft. If it bends 1/2", then it is a .500.

This is important. The arrow, if you could see it in slow motion, flexes to the right as it is shot out of the bow. After several left and right osciallations, a properly spined arrow straightens out and flies downrange. Too stiff of an arrow doesn't flex enough to the right intially and winds up coming off the bow nock right (point left). Too weak of an arrow flexes too much to the right and comes off the bow nock left (point right). The fletching will eventually straighten out the arrow, but it will have all kinds of left/right issues trying to get it to tune.

If you have to choose between a slightly weak shaft or a slightly stiff shaft, the stiffer one will serve you better. But it is best of all to have the correct shaft when it comes to spine. The HV 250 would work fine as well - but probably cut to 28 or 29 inches. A longer arrow becomes "weaker" in terms of spine, and a lighter tip makes the shaft stiffer. There are lots of charts on this stuff. Worth checking out.

First of all, sorry about the confusion between 3d/indoor. i just want an arrow that i can use for both because well... i havent found the tree that money falls off of
Thanks Roskoe, youve helped a bunch. I understand what arrows do when you shoot them, just not the numbers part and what makes what happen (stiff/weak) Also, the partabout gpi, (which is why i started this thread)i know gpi doesnt have anything to do with spine either, but i was basically trying to figure out how thisgame works so i can get the lightest arrow possible (correct spine of course) and with a big shaft. thats why i was thinking the hv350at first b/c its super light and my buddy shootsthem out of his pse (shorter draw than me) and they shoot well. I think im going to go with the HV250. would a 100gr. tip be best.
thanks alot
