ollie: I am wondering about the pros and cons of the above stretching devices. How does one compare to the other in terms of maintenance of circulation, comfort during extended wear and results achieved. I'm throwing the question open to any and everyone who has experience of these and would love to hear from you all. In particular I would like to know how wide a "sweet spot" between too tight strangulation and too loose constantly needing re-adjustment these two products have. Thanks for your help.
