For diving in the UK in colder weather the water temperature can easily be below 10C. Warm water regulators seem to be 10C +, and then cold water regulators for below that as they need to be able to limit or prevent free flow.
Is it possible (and / or acceptable) to use a set of cold water regs in warm water, or is it better to just get two sets of regs?
UPDATE: We got mares abyss 52 regs (second + octo) with a DIN first stage. Worked fine in 8C water.
