Hi, I recently asked a question about the Gamma crank stringers vesus their electronic strings. Now I've read a lot about the Wise Tensioner upgrade and that looks pretty cool. So my question is, which is better to get? A $1000 gamma electronic stringer, or a crank string and then upgrading to the wise tension head? One feature I really like on the wise tension head is the pre-stretch which the gamma does not have. It is also linear pull so it should be more accurate right? Which crank machines have the strongest and most sturdy mounts? Are the mounts on a Progression ST II top notch or do I have to get a better system? Lastly, I assume the Wise head is compatible with the gamma crank machines? Thanks ahead of time. I realize I asked a lot of questions in here, any answers would be appreciated.
