better uncut tactic: first you do not skin back, instead you close the conundrum up to letting just a small opening, so that it swells and the urine flushes the inside of the bag clean. Then you skin back and finish pissing. Did that all my life, and never had to shake it at the end and spoil my pants.
cut versus uncut conundrum. Uncut, you wash really good and skin back before pissing. Cut, you hang it out, shake a few times and you're done.
