I have 3 of the HH Expeds fpr my 2 daughters and my wife. A good friend of mine also had a Exped but he was right at 6' and decided to upgrade to the WBBB. I think you BF would do fine with the Expedition model but would strongly encourage the zipper model over the bottom entry. Makes it easier to access things that are outside the hammock versus having to get out of the hammock all together. The bottom entry is a clever idea making it easier to get in the hammock for some folks but having the zippered bug net is worth the price even if you have to have it modified. Also recommend a larger tarp but that is something he can get later on his own. The stock tarp really only covers the hammock. In a rain storm, he'll be hard pressed to cook under it.
