Bathmate x30

Hey

I have been using a Bathmate x20 for a good 6 months or so. Usually 4 to 6 days a week. I have made some great gains. I am in need of a x30 now for the size both on girth and length. I am going to use the x20 for another week or two but I was wondering has anyone had to do the same thing and I’m assuming so but does having the bigger size help get size gains better and continued. Or is it just more space? Does anyone have an x30 that I could buy as well, I am thinking about selling my x20, but I might just keep to have the parts or if the x30 isn’t good as x30 or idk. LOL. Also does anybody have any tips on using the Bathmates. I have made my own shower strap, and I have taken the white padding thing out, because it took up too much space in the tube and I could not get close to fully getting the width of dick into the tube. It has been working out pretty well with that.
