If it ain't broken, don't fix it. I think putting a traditional wand style handle on it instead of the T bar handle is a mistake. I have frozen shoulders from throwing and pulling the wand. I've had cortizone shots, extended physical therapy. I've got some of my range back but not all of it. I can lift my arms up over my head again now and reach behind my back to tuck in my shirt but it's not 100% maybe 80-85%. That's probably the best I'll be able to get. The encapsulitis has so much scar tissue built up now.. the only way to get me to 100% is for them to put me out completely and force the shoulder joint to rip apart the scar tissue to free the muscles and ligaments. Even then, the cure may be worse then the curse.
Personally, I'd leave the zipper as it is. If I could justify the price which I can't right now, but if I was in the market for a new wand and had a system to correctly utilize all of it's benefits to the max... it would be the zipper. Although, I haven't tried a
Prochem Ti wand eiher so maybe I'm speakng prematurely. But I like the idea of "mowing" a lot better than all the pressure and twisting with traditional wanding motions.
