OL Adcock invested a good bit of time with me some years back on tuning... after studying his pages on his site to that point, I still had questions.
OL claims that even 1/32 of an inch on the side plate will make big spine differences....and anything on the limbs will change harmonics and dynamics.
Yes...and I have seen it with limb tip protectors changing spine characteristics. Same with silencers, etc. Add a bow quiver adn things really change!
I've found OL's advice to set up the bow the way you want to hunt it, allt he bells and whistles on it and THEN tune it to be sound advice, fwiw.
