Bud, I just got the OCT extreme 160 and love it. Do the mesh mod. Its very tempermental and wont start unless its perfect, but once you get it done right its amazing. IMO its better than the overpriced ATI (better control of gatevalve, silencer, much cheaper, same pump).
Your going to have to blow into the airline to get it started in the sump but it works amazing once you do this. There is a bit more noise but still pretty quiet compared to almost all other skimmers IMO
Bud the mesh makes A HUGE DIFFERENCE (night and day). I know what your saying but you mine is kicking A$@ pulling some of the best foam ive ever had, and ive damn nere every reasonably priced skimmer
