Looking to upgrade, need suggestions

Hey guys, I've been wakeboarding for 2 summers, but summer 06 was behind a Polaris 750 so I don't really count it. Anyway, my family was looking into purchasing a MC x-2 when it became apparent to us that at the time we did not have the money to shell out. Our alternative ended up being a SeaRay 185 Sport w/ wakeboard package and 4.3 Merc I/O. After a season riding behind the searay I am beginning to wonder if my inability to go as big as other riders behind MC's (there are 2 x-80s that are regulars at the bay with us) and other inboards is due to the wake that the sea ray throws. I've tried everything from trim to speed to rope length and I still can't get a consistent wake and a decent pull. We have 90 hours on the boat and are seriously considering upgrading for next season because we now have the money we lacked at the beginning of this season. Keep in mind I can land pretty much any grab, HS and TS 360s, and frequently land on my head during backrolls =p, in short, what boat do you think is the best upgrade for someone looking to take their riding up a level, while not killing the wallet. Keep in mind I am in saltwater, stainless steel is preferred. Thanks
