How well do the new arrows spine and how do the bad shots FEEL?
I'm not sure I understand the question (and I mean that on ME)? I "hope" the arrows are spined correctly. I got them from someone who shoots a similar setup (#-age, bow, close on draw, etc...) and I trust their judgement. That's all I can tell you. At 20yds....I'm shooting pretty good, but the bad arrows still FEEL good. I hope I'm understanding correctly....because I really value your input on this.
I haven't changed my setup since I brought the bow home on day one. My arrows (and I promise you it's a stroke of genius and luck on the initial setup) have changed several times.....but I have only made a sight adjustment on these new fatter arrow. I've gone from target to hunting setups 3-4 times, now....and never moved anything.
I changed my #-age down to 63, recently.......but I don't know if that makes a hill of beans difference (or if it does!?????).
It could VERY WELL be just ME out of practice. I guess we'll see in the next few weeks.
I KNOW in golf.....the firs tthing that goes when you haven't played in a while is your short game. I don't know about target archery. I'm a novice. When you haven't shot past 30 yds for quite a while....I can imagine it's NOT like riding a bike.
I'm not talking about missing targets here, either, guys. I'm talking about occasionally missing a 10 ring. I hope I haven't painted the wrong picture. My last round of 20 targets, today, was 194. My last target is a standing jake at 42yds

. I also shot a fox at 28....and a beaver at 27. It's not like I'm flailing them.....but it's not where I used to be, either.
Lst bit of info....just for clarity. its not terrible....but nowhere near where I want to be (or where I was). A few months ago....I was averaging 10 points a target.
