Ben,
Happy Holidays! Thanks for starting the discussion.
I'm interested, but a carry stand bag, about 3.5 lbs tops. gives the best of both worlds in my view. Too small, and it really can't have much function beyond the quick spin use. Too big, and well...just call it AmericanTourister. Sun Mountain used to make a 3.0 lb. bag for Ping, the "L8+", which was the bomb...absolute best, most efficient bag I've ever used/seen. Of course they dropped it.
Having done the job for a living, for decades, it has been frustrating for caddies and regular walking golfers, to see the Hoofers and other nonsense, masquerading as a true carry bag, when they're down right uncomfortable in many cases. They keep trying to come up with these other offerings...none have come close to matching that bag.
The conversion option to a quality, single strap is essential. No light, carry stand bag needs a double strap, though the industry has done a nice job of forcing that down our throats, much like the soft-spikeitis mantra that leads to nightmarish putting surfaces in wet weather conditions. Oh I know, the double-strap disciples will howl about back strain, lower lumbar protection etc...have at it, for most of us over 35, you have to be Gumby to get that contraption on or off. Ever try and play while trying to use an umbrella in a breeze, when carrying a double-strap bag...the defintion of futility.
Caddies and any adult who's not Houdini, worldwide, HATES the double strap crap...nuff said.
Keep us posted!
