I just got back from the bow shop. I was able to pull the 70lbs, same as right hand, with both the tykon and the tribute. I shot them withouts sights and it felt okay but i am still leery about 1)switching right before season and 2) spending $700-$800 on a lefty bow and equipment and not being completely happy. \Tough decision for me. I am going to another bow shop tonight to decide.
