Follow the maxim of taking off half as much as you think !Thanks for that Del.
I had a look at the grip area of the bow and noticed it is quite 'square'. So I am going to take what appears to be a 'shoulder' (for want of a better description) off and make it rounder.
Nice, pleased it worked, it's great when people realize they can tune their own kit gives a better connection to the bow and more understanding. ( I hate it when people throw money at kit they they don't understand in the slightest!)I took your advice Del and used a cabinet scraper to round off the handle behind the arrow plate. Shot Sunday afternoon - not a mark on the bow at the end of the session.
On another point. How important is arrow spine for a longbow. I have found it quite critical with my recurve, but I can shoot a wide range of arrows with my longbow and they all seem to perform reasonable the same?
