Thanks! I hope so too! I think a ton of the ideas coming from individual prosthetic shops are really neat and try to figure out which of them can be mixed with what other options to make a better fit. I am working on another model that sort of combines a strap on with something like a shot pocket to act as a stroker that you can position more freely, since IMO a ton of the models that have strokers built in position them way too high.
There are some pre-existing Google doc resources on ftm subs in reddit you could port over, like from r/transmascdicks. I have a couple websites in that vein to recommend as well, I'll just need to dig them up.
Yes, I already did it to the 196 community because the memes were too much
I have only ever used it on a heavy, hard prosthetic (literally almost 1lb of dense silicone), where it works okay, and better when combined with tight underwear to support the balls on my prosthetic, using the waistband to hold it up as well; but I imagine it would be a lot more effective on a light soft packer. I also ended up kind of scratching the back of the popsocket, the part that you use some dermal adhesive to stick to your skin, so that it would attach better.
