I am considering maybe trying one of these, and have been doing a bit of online reading on them both, along with what my proshop guy told me about them both last night. Just looking for the good and bad of each one.  Currently I use an exactacator, and believe I read from turbo that the switch grip works with thumb molds....but can the IT work with molds also?   Another thing my proshop guy was wondering about is that since I am left handed, he wasn't sure if with the IT system, that releasing the ball would "unscrew" the grip. Any info on the two systems to help decide if i go with either one or just stay the way I am with my curretnt thumbs is appreciated.
