I didn't think so. I hope not. It'd be like a collision between a Miata and a guy's car.
Moving to doubles is a money pit if you're going to remain a recreational diver. Although I don't know my man, Billy - I surmised he (like me) is a recreational weenie. It adds up fast:
* Doubles Training - serious training is real dollars.
* Another First Stage
* Bands, Manifold
* Likely a new BC. At the very worst, another wing
OY - enough already! eBay those estate sale hot dogs from the Carter Administration, get over the overrated nostalgia of diving these Mike Nelson throwbacks and get a new 130.
All of your tank issues (whether they be severe hooverism, end of dive floatyness, rigging, trim, gas volume, etc.) will be solved.
I'm no hercules, and they haven't made the SoCal shore dive I can't take my 130 on yet. I mean short of scaling down a mountain, there isn't any reasonable site I haven't taken this thing on.
