OK, I'll take a shot at this, tho my experience with the Clark is much less than many others.
Keep in mind these are just my opinions only...
Suspension - for space and weight savings whoopie slings are probably the best. You still need tree straps and adjustment is not all that much easier than some other methods. I am one of the minority who am not that fond of a whoopie sling suspension. For ease of use, web and buckles are hard to beat and they are their own tree straps. But they take up about the same space and weight as the stock suspension.
For hanging - hang it - get in - close the zipper. If the zipper is hard to close at the finish you are strung to tight. If the netting is loose after being zipped closed, the hammock may be too loose (although you might find that more comfortable). Main thing is be sure you are not so tight you stress the netting - just go something less than that to find a comfortable hang for you.
Then - after you find the right tension - get out, close the netting and storm shield, and take a look at the hammock. See how low the storm sheild droops towards the hammock sides and try to get that droop each time you hang. If the low part of the droop is midway between the hoops, you are nearly level. If the low part of the droop is at about the 1/3 way going down from the hoop at the head end, you are hung with the foot end elevated which is the preferred angle for most.
There's so much more. I can't wait to hear others chime in.
