So I got a chance to dive the MiFlex hoses tonight. As for my primary regulator, I don't really have anything to compare it to, as I don't have a hoseless second stage. (Yeah, just about *that* good.)
I also swapped out my pony's--
Oh, nuts. The cat just came inside with what appears to be a rodent that failed its Evasion and Escape course. One moment please...
...*muttering and gloves*... aw, *crap*, it's only *mostly* dead... (Yep, this here's real life intruding, go figure.) ...*more muttering*...
Okay, so as I was saying, I swapped out my pony's LP hose (a standard recreational short primary). With the original rubber hose, it was uncomfortable to left-sling the pony (as is my standard operating procedure), as the hose leaves the first stage going down (for proper hose stowage) and enters the second stage from the right (I use an AquaLung Titan). It's not exactly comfortable, and when I had a slung AL80, it was downright uncomfortable (I held the hose to lessen the strain). With the super-flexible MiFlex hose, it's a whole new ball game.
Anyway, with the new MiFlex hose, it was amazing. One of the instructors who was there saw my pony with the MiFlex hose and said he needs to get one to try out for his slung bottles. For slinging, I don't know that I'd ever want to dive with an old rubber hose again. I've never had too great a problem with my primary second stage's hose (perhaps because I have the tank mounted high enough to reach the valve, so there's less deflection), but for a slung pony, it's really all that.
"Johnny wants a pony, but Johnny's pony wants a MiFlex."
What length hose did you use for your slung pony? I'm guessing the 36"?
Generally deco bottles use 40" reg hoses... I'm wondering if 36" is enough, because 48" seems like way too much.
