If you mean you will keep looking for a more comfortable seal for the gravel tube then take a look at post #18 in my make your own pump thread. I’ve described in detail how you can make a flange type of seal which is extremely comfortable,.. I give it a 9 out of 10 comfort rating. Since it is a closed cell type of foam it provides plenty of cushion where it contacts the pubic bone and I think it allows you to apply more vacuum without sacrificing comfort which makes for a more intense pumping session than what a Plasti-Dip seal would. Let me know what you think and if you have any ?’s I’ll do my best to help.
