Believe it or not,that double set is WAY better than it used to be and I no longer shoot competively so I am less concerned as I used to be.My coach(level 4)was actually just a friend that gave me pointers from time to time,never actually gave me a lesson,unless you consider the conversations we had lessons.
He told me that he didn't like it and that I needed to try and fix it but he knew very succesful pros that did it and couldn't/wouldn't change,so not to be overly concerned but I did need to work on it.
I mentioned the double set once before when I posted the videos.
I liked shooting a little longer with my longer a-abow but it also had longer limbs and the feel was completely different,Also,it was competition exclusive and this setup is hunting/3-d.
