Need advice on tube upgrade from 357

[Someguyoverthere]

Hello,

I am currently using the Bullmaster 357 and I am looking to upgrade. Currently I fill the 357 about 75% but I am starting to have trouble getting out. My focus/goal is on testicles specifically (not scrotum) to be larger and have more sag. I understand that a two-stage tube would be ideal for this more so for the size. However I feel that the 3" entry the 357 is about my max because I believe any larger would cause to much pubic area to get pulled in.

I would like to consider the Bullmaster because I really like the shape of my 357 but supply chain issue. Again I worry about that 4" opening will allow to much pubic area to be pulled in, but will be easier to get out of.

So I am currently looking at the 3x4.5 from Boston pump or 3x5 from La pump.
Are these two-stage sizes I am looking at a good size to step from the 357, or should I consider smaller or larger?
Is a seal require for a two-stage?
How does the quality compare between Boston and La?

I know the Monster tube jr is probably the best option because getting out is nothing. However the price is a hard pill. Also does it require a seal?

So what should you advise?

If I were you, I would stick with the 357 until spring. Around end of March, sun tea jars will be widely available again and you can easily build your own using the stj conversion kit from pump toys. You’ll need their seal to go with it.

I would advise against the two stage. You will definitely get stuck, unless you’re willling to spend the cash to buy all the sizes (3, 3.25, 3.5, etc) and move up through them as you grow within a session. Which is a pain to do.

You shouldn’t get stuck in the 357, even when packing it, provided you’re lubing up properly (lotion or conditioner) in the tube and releasing the vacuum. You could also try gently blowing on the tube to give yourself some extra pressure on the way out.

Go for a tube with 4" opening and get a seal...
Silicone seal from Pumptoys or the Juicy XL.
I have only tried the seal from Pumptoys.
I have never liked 2 stage cylinders, as you get a problem to untube from it when your balls grow big...

From a 357 to a Magnum it's a big step! You could try to get your hands on a used standard Bullmaster....

Take a good look at the pictures on pumptoys.com where the measurements on both standard and Magnum are written.
As you might know it's possible to order both tubes in different lengths....

If you find some kind of Bullmaster, be sure to know what length they are!

If you want a tube you can use for many years, why not go for a STJ?

If you compare a Bullmaster Magnum vs STJ, the STJ for the biggest volume.

I meant to say the Bullmaster and not the magnum. Sorry
