Agree, fit is the most important factor.^^^ Most important factor
As well as the seams.
You will never know how bad your suit fit until wearing a custom.
Even more so if you try an OTR suit after wearing a custom - nothing will seem to fit and you will instantly recognize the areas where the suit will wear prematurely or the seams will go.
I was talking to a guy in an Axxe about this today. He said he's tried to explain this to his friends but they just don't get it. Great fit, no leaks (ever), better quality neoprene. They'd rather spend $400+ for a crappy new suit every season.
