I am looking at the warbonnet blackbird double 1.1 and one of the hennessy's (need help on selection) with the zip. I am 6' and 230lbs so it needs to be able to hold at least that unless they are conservative with their weight limits. what will be my lightest and safest choice? its hard to find out because the HH comes with the fly. I have no problem changing out the suspension to whoopie slings either. Thanks for the help in advance.
