I've pissed and moaned for years with a cheap spotter setup so I'm springing for a decent straight spotter. I'll use it at the range, glass for moose while sitting down and occasionally haul in a backpack. So many tripods on the market and they all claim to be the best. Any testimonials on a durable, packable tripod that can do it all without breaking the bank or having to hire a Sherpa to haul it around?
