I'm 6'2 and do glass standing up often, without having center colum 24L covers me for that.
When I talked to main guy at RRS shooting division he mentioned might have something new coming out this year for glassing/shooting.
U could also run a seperate head on top of a anvil for glassing if set...
Great build and not too heavy.
For glassing 95% of the time and shooting when needed, the ball head is a easy choice for my hunting.
Too busy with work to get to use it, very little field use so far
I want to say the hunter bolt is smaller than the 8400, nevertheless it looks great.
I put Ti tactical knobs on my kimbers. Makes grabbing with gloves a breeze. My brother has the carbon knob from Lumley/bolt knob.com
