When I made the part of the time switch to left hand, I found that my form needed slight changes from doing the exact mirror of my right hand. There were different tendencies. one being, my anchor would get too high on my cheek, which caused an imbalance in my release fingers. Another was that my neck does not rotate the same to the right as it does to the left, shooting thousands of arrows a week for 55 years can do that, so I had a different eye to arrow to target picture that I had to work out. Also, my draw length with perfect form is 1/2" shorter left than right, if I try to force the 26 & 1/4" plus on the left that natural feel for the target is gone. On my Schulz bows exactly 1/8" up from 90 is the sweet spot with wood arrows, anything over 3/16" for me would definitely show up in every shot. The biggest mistake i ever made in archery is not taking John Shulz's advice when I ordered my first longbow, I went heavy because I was very strong at the time. I later bought two 64@26" bows from John and I should have started out with the 55 yew he suggested. Then in later years I thought that I could really use a 55 pound Schulz legend to go with my 64 pound legend, I messed up again and got another heavy bow to go with my other 85 to 96 pound bows. The one guy that lived about an hour from here did not like me to even look at his 52 pound Legend. I think he was afraid that if I ever got my hands on his bow, I could out run him and he would have been right, he had short legs.
