I took delivery of an all-black Flex Extreme last week and had the chance to put my first dive on it last night. Awesome suit - very light and flexible, but clearly hardier than the TLS350s that many of my buddies dive. I opted for rock boots, which required a move up one fin size, but despite the slightly greater weight and different feel from my last suit, there was no difficulty getting comfortable and maintaining good trim. This is a great suit solution for a diver like myself who dives dry year round in the Great Lakes..
