Go with Manfrotto like so many other folks that rely upon their equipment for their livelihood. The one biggest thing I've learned over the years is that up until recently the best equipment you could buy for hunting was not hunting gear (other then your gun, ammo, bow). For clothes, boots, packs, tripods, tents, sleeping bags I typically only use high end mountaineering equipment. Fortunately there are a few companies out there that are finally making high end equipment for hunters.
Here's a link to the Manfrotto tripods. Good luck.
