I don't know HOG regs, but as I am now in the market for a second reg and first stage for a second cylinder I will have a look, but for my two pennyworth I went with Scubapro, a MK25/A700 setup and I do really likel it. It breathes real easy, and feels very well made. I also went with a Scubrapro BCD, a T Black - again bullet proof in terms of build quality, but it is very heavy and bulky. The fit is fine and very comfortable but the pockets are difficult to access, particularly if you have a lot of weight in the intergral pockets.
I travel a lot, and am almost always flying business, so the weight is not a major issue, but this certainly would not be an easy BCD to travel with otherwise.
Jim - thanks for the comments on BC/W I have been thinking about an alternate BCD for travel and something which can 'expand' with time might be good. BTW I have just completed both CMAS 1* and CMAS 2* programmes this year at the grand old age of 49 ! so there are a few of us late bloomers out there, hopefully there are many happy years diving ahead.
