I'm using the stock tanks in Funtana (gave away, don't own it anymore) Showtime, UCD60, Hanger 9 Ultra Stick 120, Yak, and the Mayhem. Some of those are DuBro tanks but they are the stock one with the plane. I've heard a lot bad about the stock tanks not holding up to the pressure of the YS. So far, I haven't had a singel problem. I'll keep using stock until I get burned. Shouldn't take too much longer. But the stock tanks work, at least for me.
THanks
