A buddy is looking to start stringing his own rackets, and I haven't used one of these myself. Can users/owners comment on this machine? Personally I may have gone with the Neos 1000 or 1500, or the Gamma 6004 with the SC mounts and super quick base clamps. But he likes the idea of the constant pull electronic tensioner. How are the clamps on the ELS? Is mounting on the 6 point a little tedious, and do the arms tend to get in the way when doing the crosses? They look a little beefier than others. Thanks all!
