Not so easy as it may seem:
At 10lb less than your weight and 4" less height, I find the 8' models, which included the NX150, plenty long and comfortable. I'm an every (dry) night hanger, too. The NX250 is more than I need, especially after weight loss.
OTOH, if you intend to use the pockets for insulating pads, especially your own, be aware that on the NX150 the total width of the 3 pockets pockets adds up to much less than the 46-48" length on the NX250, which is the size of a typical fractional UQ.
Note that Clark has a third size hammock body,intermediate in length between the 8' and 9' models. The Tropical and (cheapest) "Ultra-Light" now share that 8.5' length with the North American.
