Selecting the proper cylinder size is important for making your pumping sessions both comfortable and rewarding. Your cylinder should be large enough to allow for significant expansion, but not so large as to make it easy for your testicles to be drawn into the cylinder by the vacuum.When selecting length, choose a cylinder that is between 2 and 3 inches longer then your bone pressed erect length.

*If you are at the upper limit and are going for length, select the cylinder diameter straight across in the table. If you are at the upper limit and are going for girth, select the next cylinder size up. Example: Your base girth measures 5.25. If your goal is length, select the 1.75 cylinder. If your goal is girth, select the 2.0 cylinder.
This is what I referring to. GPRENT did us a solid with his table. This combined with what I’ve read from Titleist looks to be a promising endeavor.
I would suggest for those who are looking to start pumping if you know anyone on Thunder that has s similar body type as you who has seen success, it might be worth while to review their efforts. No need to reinvent the wheel people. That doesn’t mean other people’s results wont be beneficial either. Knowing your body type doesn’t only work in body building or weight training.
