Looks like i landed at the right spot for info.

I've been backpacking for over 30yrs and have always done so in a tent.
I have top-line equipment but recently have been having restless nights and waking with a stiff back.
Do i sound like a prime candidate for a hammock?
I'm a back sleeper,are they really that comfortable?

I've researched for a couple of evenings and have narrowed my search down to:
Hennessy ultralight
Clark ultralight

I do the AT,Smokey's,most of WV/VA which is why I'm looking at ultralights.
Would one be noticeably better then the other?

My last question is going to be strange.
Can a dog "50 lb" sleep in a hammock with me "165LB".
I'm serious....my border collie has packed over 1000 miles and is an incredible trail dog with manners and a great companion and has always slept up against me at home and on the trail.
Thanks
