I'm planning to upgrade my regs and have narrowed my selection to the Atomic B2 or ScubaPro MK17/G250V. I like that the B2 can switch between air and nitrox without additional cleaning. Would like to hear from users of this reg if the environmental seal kit is really required to dive 35-40 degree waters I'll experience at Tobermory. Does sealing the reg cause any headaches?
