I’m just about where you are in length and a 10” tube works well for me. 11” inches may not be “standard” for some makers and could cost you more. Keep in mind that I don’t pump just to see how large I can get in the tube. I’m only trying for some period of girth/length expansion after my PE exercises. If you normally are 8.5 L, you might reasonably pull another inch in the tube over an extended period of time, if that is all you are looking to do. That would put your glans very close to the inside nipple and you don’t want to be pushing against that. Girthwise, a 2 inch tube sounds ok, and you’ll have room to grow into it.
Consider, too, that an hour of hanging and an hour of pumping are not at all equal exercises. Pumping is a totally different process. You could probably achieve in three, 8 minute sets of pumping at a reasonable pressure more than in an hour of mostly pumping.
The guys who just pump for the sake of looking long and fat in the tube don’t see those same results in sexual erections. It’s like a mirage. You see this monster you’ve created, but release the pressure or try to duplicate that with a plain, old horny erection and that’s not what you get.
2in2000 has a nifty idea there. Your nocturnal erections may be larger than normal. I’ve never tried that since I do all my PE work early in the AM.
