I've owned a Ranger LTD for about 5 years now. So far it's been bulletproof except for needing to change a sticky inflator ($25) last year. Probably lack of cleaning on my part. Best thing about the LTD is the Lumbar pad, it makes floating on the surface almost a pleasure. My buddy has a regular Ranger and he added one after seeing mine.
While waiting for the new inflator on backorder, I bought a Stiletto, thinking that it would be easier to travel with. It likely is, it's smaller and just fit into my airline approved roller bag - as long as I didn't pack much else in there.
Can you change the wing on a Stiletto? afaik most of the Zeagle wings can be changed on the Ranger in a couple of minutes. So if you go to doubles, you could buy their 65 lb. wing if needed.
Both were equally well-made and fit well but after thinking about it for a couple of days, I returned the Stiletto unused.
My reasons:
Since all my other gear wouldn't fit in my roller, I'm always checking a bag anyway. Since my fins won't fit. And I like to change clothes daily. Especially in the tropics.
I travel with regs, video gear and some non-dive stuff in the roller bag and most everything else in a heavy-duty non-dive logo'ed rolling duffle bag. Stuffed full with stuff I invariably wind up bringing back unused it tops out at about 45lbs. max.
Maybe it's just familiarity but the Ranger was more comfortable in the shoulders than the Stiletto with weight in it. I never tried it with a tank though.
hth,
