I wouldn't if you were trying to avoid discoloration. Most of my dark color has come from vise/compression hangers. BIB's a good guy though. He makes an excellent product...and has a no questions asked warranty/replacement policy. He also gives free hangers to men who help move his product Nothing wrong with that either.
Blistering problems from vac hangers, I've found from ACTUALLY USING THEM seems mostly about how much vac you're using, and how much
weight/resistance. If you are not using enough vac to get the glans expanded in the front of the chamer fully...you will get a blister most likely. Also, if you are using too much resistance too soon, same deal.
Hanging has its' challenges, and risks no matter what device you decide on, but if I personally had it to do over....and had the vac hangers available when I started
hanging on again, off again 9 years ago...I'd have gone with a vac
hanger.
