Not the total end of the world like old skool metal-to-metal connections. But much less than ideal for the reasons @PfcAJ mentioned.I'm aware of stage bottle rigging from Halcyon and Dive Rite. Obviously the Halcyon product would be fine with GUE divers. How about the one from Dive Rite?
I'm talking about this: Stage Bottle Rigging Kit - Dive Rite
I ask because I want to learn how to use a stage bottle at some point. I need to spend more money at an online shop before I qualify for free shipping. I could buy the rigging now.
Personally the giant clips can be helpful with thick dryglove liners on in bitter cold water <5C, except I rarely wear super thick dry glove liners anymore. I use suit heat to keep me warmer overall and can get away with thinner liner gloves - mostly so I can write better in survey notes. The side benefit is not needing giant boltsnaps everywhere.
I would pass on the diverite kit
