I haven’t done any P.E. in several months, but was getting great results from clamping. I regret not “cementing” and being too lazy to continue. My most memorable moments were getting over 7 inches near the base.
I was clamping for sets of 10-20 minutes a pop with total clamping time of 60-120 minutes a day before I stopped. I found it critical to use 2 clamps instead of one, it made the intensity more controllable and minimized if not stopped any fluid buildup. After grueling trial and error of finding decent wrap that I could leave on, I cut up a waist trimming belt into 6 inch strips and took a hot glue gun and made some super “cock rings” that could be left on between sets. I also hot glued the clamps together and took an electric grinder to the “ear” and teeth I didn’t need.
I found it extremely helpful to apply Vaseline around the base so I could “bury” the clamps in my fat pad, without lube this is almost impossible.
As far as length, I think it would be important to direct the pressure upwards on the shaft, hence two or three clamps. This point is just my opinion, I believe the base is more susceptible to modification(weakest?) I would much rather use two to three clamps instead of one, the pressures are buttloads easier to control requiring less tinkering and it also kept my base from “blowing out”
Nice to see you fellows and congrats to all the new Moderators.
