Right now, the main thing holding me up on a Clark Hammock is the 200 v 250 question. Based on the pictures, it appears the 200 has more headroom when sitting up, but the 250 has more "elbow room" when lying down. Presumably, I will spent more time in the recumbent position so the 250 may make more sense.
The 200's rain fly is attached and I don't understand the benefit of this. Clark seems to think it is convenient, but in the rain I think it would be more convenient to set up a fly first, and then the hammock. Packing up in the rain would probably go easier also if the fly were the last item taken down.
On the other hand, the 200's fly with its additional lines looks like it may add to the stability of the hammock. However, the 250 seems to be roughly the shape of a Blackbird, which does not have a 200-fly setup. Blackbirds sound like they are stable enough.
Clark says they will continue to make the NA/200 hammocks which have "stood the test of time," but I am wondering if the 250-type may turn out to be the NA's sucessor.
Not having withstood the test of time, the 250 is more of a gamble but since I have never been in any hammock before I will be gambling anyway. Even so, it is tough to decide between these two.
