Spine...Is it really true?

[Curveman]

Yep, plus many don't know what good tuning "is" and say they are well tuned when they are not....O.L. [/QB][/QUOTE]
That would be me!     That's why I always have someone stand behind me when I am tuning and look for what I miss. Some people like tuning-I'd rather be like one of those rock stars who have their guitar tuning done by a roadie and just handed to them!   :D  
That being said, I have been shooting these 545gr 55/75 GT's with all the weight up front. 29" Now, I just bought these woods, 28.5 inches 75-80 in spine with 145 up front. 610gr They both seem to fly great out of my 62# Border Griffon longbow that is not cut to center. Now I'm paranoid though. I think you guys would be going: "Whoa! He's WAY off!"

Curvemean,

I can relate. I don't find arrow tuning to be any "fun" at all! It's sometimes just plain frustrating! Like broadhead sharpening...I do it out of respect for the game...but it is often a pure tedious PnA!  

I used to be what might be termed a "arra ho" and had every thing imagineable in my quiver... different types (alum, carbon, fiberglass and wood) in different weights, lengths and spine.

When I did my part...they all hit the same relative place...

When I first started BS testing using that planning method...they were ALL weak...way weak!

That's when the light came on. When I was solid footing, standing up in the yard, I was dead on...but not always from a stand or other contorted field position.  I was in those "tails" of the standard distribution of bow/arrow tune that OL's site speaks to!

I had dozens of folks stand behind me, on steps, on ladders...etc and they'd "never" see the occasional subtle "kick" I thought I saw.

The planning method showed me "WHY" I saw that kick...I must have had a reasonably "consistent" release to get any decent flight from those mis-matched batch of arrows.  That and restricting my shooting to 20 yards! Shooting farther shows so much more...even though I won't take that shot on game..it shows tuning issues better!

So many of my friends, even today, say if they hit where they're looking and fly decent...they're tuned and good!      

It's amazing on a simple stick bow, how many li'l things can be tweaked to get that "best" (not just good) arrow flight.

Perception is one thing...duplicatable results can be something else!

I swear by the bare shaft planning method, but it can be a conundrum at times and I have to be shooting well for it to work. I've learned to not just shoot one group, or 5, but on different days before I start messin with stuff.    

Seems I'm the most variable variable in my set up!

Let me throw another variable at you. A bow cut 3/16" past center, using small dia. carbon shafts will actually have the center of the shaft past the center of the limb making tuning more difficult, you will have to move the strike plate out some just to achieve center to center (shaft & limb)

Bob,

I'm shooting the GT5575 and that is about .001 thinner in dia. then a 2018 I used to shoot...so not really THAT skinny, per se.

W/ 5" low cut shield, I get great flight...but when I tried the smaller, quieter, the annomolies started to show up...and I went 3" instead of the recommended 2".

OL put it all in perspective with his statement about "don't know which way to paradox". Just kinda makes sense!
