It's hard to decide whos opinion is worth more, some random joe on the internet or the guy who runs your LHS. It can take a bit of time to really see who knows what there talking about, unfortunately the one guy most people rely on, The Hydro shop guy, in this case was dead wrong and by a mile i might add. Either way now u know to take his advice with a grain of salt, and hit the forums a bit more, and hey, now u have some one with real experience and know how to help you out, 99% of the time most people on here are willing to go far beyond what u would expect in terms of help, and when its appreciated, people will never get sick of ur questions and problems.
