I shoot a trykon at 68# 31" draw length with gold tip 5575 at 29",100gr tips and a wb quick shot. My problem is I was triing to paper tune today and im getting a 2" tail high tear that i cant get rid of. I tried to move my nocking point down a little at a time till the aroow tip was way higher then the nock and still no change. im stumped and any help wuold be much app.. Oh and i do shoot a release with a loop.

those arrows are about a .400 spine. you need to be shooting the 75/95's at least.

thanks for the advice giblet but if you look at the charts it falls under the 5575 catagory. I have one more question though on them charts the length listing is this your draw length or arrow length that your suposed to use. I have some cx400 also but according to the chart they are over spined for a 29" arrow.

gibblet

a .400 spine arrow is too weak for 68#, 29", and the force generated from a 31" draw. there is no way around that - regardless of the chart. the 75/95's should solve your issues, or at least get past the ones related to arrow spine.

not only are you under spined, you are severely underspined.

what about the cx400's?

I have a question:
Does an overdraw slow your arrow speed down? Shooting 65# 29" draw, with the whisker Biscut, carbon fury arrows 4" vanes changed to 2 " Blazers. trying to get a tighter group at about 35-40 yards.

gibblet

are they a .340 spine? will be a lot better if so.

I dont know if the are a .340spie or not but the carbon expresss' spine out to over 80# at a 29# shaft length acording to the chart. I dose not seem that you think theese charts are accurate so what is your take on these shafts?

gibblet

the gold tip chart is known to be off by most of us. i don't know about the carbon express chart.

I'm not sure, it's acarbon fury 6075. How do you determine the spine?
