If you Pm mat negosh on face book he's on Hawaii spearfishing and freediving page. he has a nor Easter Wong for sale send me your number and I'll send you the pics he sent me its a sweet gun and pretty good deal I would have bought it but it's an open track.
I have 2 guns both about 60". The ulusub 150 is awesome, and I bought it to use as an "all arounder" gun. However, I recently aquired a Wong GR Plus Hybrid, and the semi enclosed track makes for a better all around gun. So I would prefer to have a different length Ulusub. If anything, I will just rig the Ulusub for blue. I live in Hawaii, some of the clearest waters for hunting, so I typically go for larger guns.
