I am going to order a new winners choice string and cables for my q2xl, and have a few questions that I hope you all can help me with. I notice that the strings do not come with the speed nocks installed like on the factory zebra string. Do you crimp on some brass nock sets in the same place or do some of the rubber speed buttons I have seen work just as well? Also, I want to have the cables served in the cable slide area which they offer. I shoot a 29 inch draw with a string loop. How do you measure the area that is to be covered with the serving? If any of you shoot the q2xl, and winners choice products, how do you like them, and are they worth it? Thanks for your replies.
