Well after much lurking and reading I finally decided to listen to the multitude of advise here and walkback tune my bow with broadheads. Field points didn't show me a thing and my bow shot very well with them. I could however see/percieve a slightly erratic arrow flight as it started to the left of target. I am a release shooter but I also tried bare shaft tuning which also seemed to indicate a left of target arrow flight.
I fired several shots to get a baseline on my bow. All groups at 10 20 30 yards indicated the rest was pushing the arrow to the left my groups looked like this "/". The error was most prevalent at 30 yards thus leading me to believe you need a fair bit of distance to walkback tune. I moved my biscuit a shade to the right and voila, my groups shot almost straight up and down. Also, my percieved erratic leftward flight was no longer there. My arrows "looked" like they were flying straighter. I do believe I may have to work on my knock point but I now have confidence in my centershot tune.
I promptly came inside and finally registered to the site so I could post this. Let me thank those here who contribute their experience and advise.
