I'm also new to hammocking but i might be able to help a bit!
I bought a GTUL a few months ago and so far it seems to be a perfect starter hammock. When first got it I had no complaints (Besides the suspension), but when i set it up and got in with my pad and sleeping bag i started to realize it's a little bit narrow and i had some trouble keeping my feet from slipping out of the hammock. But i was able to fix that problem pretty easily by playing with my ridgeline and just some more practice getting situated in the hammock. And although i wish the GT was a few inches wider it is still extremely comfortable not to mention an amazing deal!
If you are trying to bring down your pack weight i would HIGHLY recommend upgrading the heavy S rings and rope they use for the suspension to something like http://arrowheadequipment.webs.com/a...s/show/2575039
. For me it seems like the perfect system, Light, and really easy. My hammock with this suspension system comes in at 13.8 oz and if i remember right (I could be way off I never wrote it down...) the stock GT weighs ~11oz. And that's without rope or tree straps..
Ohh, I'm 5' 10" 230# so the GT should have no problem supporting you.
