RE: Paper tuning???'s . . . all over again. . .
I like paper tuning but I NEVER compromise center shot to achieve good paper tear.
The 3 biggest reasons for a paper tear is torque,spine and fletching contact,There are other things that can cause tear but when you go beyond these 3 things,it gets real technical and probably isn't worth the average archer to worry about.
You have fletching contact that should be equall so we can eliminate that as a possibility.
The reflex hasa riser that can cause some torque issues so I would try many different hand positions and see if the tear gets better or worse.Try to keep your palm out of the riser as much as possible.Also,make sure your not putting too much pressure on the string with your face,this can also cause a tear.
You never said what your draw was so I can't say for sure it is spine but I am leaning toward this as your problem.Try backing your poundage down to 60#'s and see what happens.
I will almost always have my bows shooting near perfect bulletholes and never move my rest left or right of centershot.It isALMOST always spine that causes tear FOR ME.I do,however,use an archery program to select what spine arrow to use and itusually eliminates spine before it is a problem.So I usually don't have a problem with paper tear anymore.
Funny thing,my current bow, Xtec,HAD a bad tear right and my arrows are slightly overspined so I wasn't too concerned.I don't use string leaches or anything and had some severe string vibrations(severe enough it would slap my wrist and no my draw is not too long)I use 452 plus,I think, and there is no give in this stuff.I was messing around with it one day and a friend had an sts and so I tried it.It took the vibration out and the tear. I put an sts on and never looked back.
