Dirk,
I use a vac hanger also, the Max-Vac, and currently hanging 10.5lbs mostly SD and SO. Using 10.5lbs I don’t feel fatique either after a 1hr session PM (hanging 2-30min sets), (1-30min set AM). But some months back I was using 11-11.5lbs with this hanger and noticed some really good fatique setting in in the second 30min set.
10-10.5lb range dosen’t do much for me fatique wise but the higher weights do bring on the fatique (velcro ripping) in the shaft but not at the base/ligs. Of course with higher weight comes the problem of swelling/blisters and it gets worse the higher you go! I wrap the head with sports wrap to protect from vacuum effect, not 100% swelling proof but really does help minimize the effect- I haven’t had a blister yet.
You say you notice a stretch using 10lbs, that’s good, have you noticed any gains- BPFSL or BPEL? If you’ve been at for any length of time you may actually be making progress. I’ve been at it (again) for 1.5 months in the 10-10.5lb range and have gained 3/16” BPEL and 3/8” BPFSL so this lower weight is working for me.
Yeah, don’t increase the weight until you have to. If you can make progress/gains at the lower weight- 10lbs, all the better, your dick will thank you for it.
As for more time or more weight, I’d say give the 10lbs a chance for at least 2-3 weeks and see where you’re at gain wise, a month would be even better. After that, if you don’t see any gains or increase in flaccid hang (stretching the ligs) then upping the weight 1-2lbs would probably be in order. Also, if you could get in more hang-time maybe 1.5-2hrs p/d with an ADS/extender after sessions should help alot also. Just my 2cts worth.
