My comment will be towards the tuneability of the BowTechs. With the Duallys, you can change the draw modules in about 2 minutes and no bow press is needed. The modules are available in whole inch or 1/2 inch and run about $16.00 a set. If your draw still needs a little more or less, you can twist the string to get what you need exactly. As others have said, the BowTech factory string and cables by Stone Mountain are all what BowTech claimed they would be and IMO are nearly the same as Winner' s Choice products. From what I' ve seen with the 5 BowTechs I own, the birth cretificate that is shipped with the bow is very close to what the bow will do. I picked up 7 fps by going to another 1/2 inch in draw length by using the next size 1/2 inch module. Good luck!!
