Labman, I"m not seeing any trouble with Tiller at that nock height, and I've consulted with quite a few serious target archers that claim you can shoot an arrow off an elevated rest or off the shelf without adjusting tiller.
The ILF/OLY rigs can adjust for tiller, and when you are at THAT level, you just may need it, but when i'm shooting a measely 230-260 indoor round, I dont think its going to effect me. I'm getting great bareshaft flight...so I'll get great broadhead flight when the time comes...
Rob...its hard to argue with the arrow close to hand stinctor theory, but I am shooting this rig pure stinctor right now and shot close to my best 300 round last night with a hunting weight bow (249)...nothing to get excited about for many, but it was for me!!
I'll keep playing with her... last night I ripped the flipper out and stuck a T-300 on her...now I guess the holes there for no reason... ooops.
