Not to be repetitive but then why not? Everyone else is. I like the AL Titan LX> Core Supreme>Helix Pro regulator series very much. It is relatively simple, proven design, very high performance, reliable and the first stage is not only an evolution of the Conshelf it also has the ACD feature which I like regardless. For a major manufacturer product it is also relatively inexpensive.
Reaffirming my regard for the series, I just returned from Cozumel where I had a G250, a G260 and a Kraken equipped with a Core second stage for an octopus. If I was pressed to say which second stage (regulator) breathed the best (subjective indeed) I would have to say my Core did. Okay, okay, the G250 on a Mark V or X is the best ever but the OP is looking for a new regulator for travel and recreational diving. The new Helix Pro is it, it is also very compact first stage, sleek second stage and light weight set for easy packing for us weight weenies.
