I am a newbie, and I have the bug. I purchased a inexpensive hammock at walmart with a integrated bug net, just to see if I like it. I do, and I have decided to buy a better quality hammock, since I know this one will fail me sooner rather than later. I have been researching the Hennessy expedition zip. Is it a good hammock for a beginner? Will it last? Will the included fly be big enough to keep me dry? Or should I upgrade to a bigger fly. Thanks for your help
