I'm in the process of selecting a hammock. I went to a local hang today, but by the time I arrived (1330), everyone but one Blackbird owner had already departed. I had hoped to see both a BB and a RR.

So, before I decide to take Brandon's suggestion and order one of each and return the one I decide against, I thought I'd ask a question or two of those of you who have experience with both ...

When you are using your RR, what do you miss about your BB? And when you are using your BB, what do you miss about your RR?

Which do you find better for sleeping on your back? I sleep, mainly, on my back, but move from my back to either side after the pressure/soreness in my upper back (between my shoulders) wakes me up.

Which do you find better for sleeping on your sides? I don't last long after shifting from my back to either side, because of bad shoulders which usually ache anyway, but especially after the pressure of lying on them for a while.

Comments/insights appreciated.
