Well, I didn't mention the specific issue he was having with the weight belt so as to keep the replies focused on his solution, namely, the plastic QR.M_Bipartitus:I am also interested in what the specific problem with a normal weight belt is.
Myself, I had trouble with a normal weight belt. I'm bigger thatn the average diver and thus need more weight and... well... my figure doesn't suit itself to a weightbelt. When doing my drysuit class I kept having the belt end up around my knees. My solution was to get a DUI weight and trim. A bit more expensive than a typical weight belt, but it won't be sliding off.
But, since so many asked, yes, it is ending up around his ankles by the time he duck-walks back to the trucks.
(BTW, I also love my DUI weight & trim)
