I'm starting to accumulate stuff for a Muley/antelope hunt this fall in Wy. I am looking for a good lightweight tripod since I will most likely be walking/glassing quite a bit, mostly from sitting position. The spotting scope is a straight model, not angled eyepiece. Now, once the tripod is selected, what do I have to know about the head, or is it a package deal? Since I really would like to only buy the tripod once, I'd rather spend a few more $$ right off the bat than not be satisfied with a lesser one and have to upgrade.
