Close here - I use a G811g with LW tri with usually fully extended legs and I have been very surprised by the low vibration for visual use. If the wind is really strong/gusty I do notice some bounciness.
I agonized over the decision between the LW and HW and have been happy with lighter load to carry into the backyard or better sky sites.
I'm glad to hear that the LW tripod performs well! Do others have similar experiences with it?
I currently own a G11 with the Folding HD tripod. Like astrohamp said, all versions of the HD tripod are essentially bomb-proof. I would go even further and say that the HD tripod is probably the cornerstone of Losmandy Mounts' stability (especially when loaded with lots of gear).
But that said, I've been thinking lately about migrating to the LW tripod.
The reasons are that I'm already in my 50's and then injured my back a month ago. So while I seem to have recovered well enough for normal daily activities, I'm still quite concerned about re-injuring myself while hauling the (one-piece) Folding HD tripod in and out of my Subaru Crosstrek. To make matters worse, my FHD probably has another 5 lb on the bottom end, due to some foot modifications I made to improve its friendliness to flooring during handling. And of course I don't expect to be getting any younger.
To make matters a little better, I long ago realized that holding the bottom of the legs with a hoisting strap (like holding a dog by a leash) was a great way for me to remain upright and symmetrical while loading the folded tripod in and out of a car (if you have this sort of trouble, a $15, 4-foot nylon hoist sling works REALLY WELL ).
But any way you look at it, my folded HD is 4 feet long and more than twice the weight of any component in my whole setup (I have the quick-disconnect that separates the 18 lb G11 Dec Axis from the 18 lb G11 RA Axis for handling, I use only 11 lb and 7 lb counterweights, and my OTA's are in the 10-20 lb range). So a sturdy tripod around 20 lb or less would represent a huge improvement for handling.
I've considered using an LX-200 tripod with the Losmandy adapter (I once had an LXD-650 mount, which used a variant of the LX-200 standard tripod). These are actually cheaper than the LW, quite stable, and not dramatically heavier. But I do like the way that Losmandy tripod legs clamp at the top, and I don't mind paying more for the LW if it's lighter and works as well.
Hearing about similar experiences with the LW tripod would be greatly appreciated!
