Do i think think it makes a big difference...no. But if you want to be technical then yeah it will make for smoother shooting...But if Mathews dont have a new inovations then they dont have a product to sell...So its a little bit of biz along with adding newer technology, which is why Mathews are who they are...I have the Legacy and i think the best inovation they have is the string supressors...I would pick those of the roller gaurd...but if you can have both then ya might as well just take it....thats my opinion..
