Spotters Advice Needed: Vortex Razor Gen 2 vs Leupold SX-4 Pro Guide HD 2

[Perimeter]

I am about to purchase a spotter and need some quick last minute advice. I am torn between the following:

• Vortex Razor HD (Gen 2) 22-48 x65 or 13-39x56 -- both straight, not angled
• Leupold SX-4 Pro Guide HD (Gen2) 15-45x65 or 20-60x85 -- both straight, not angled

Primary use is glassing for competitions (long days on the glass) and then some long range observation. Yes I know, a good pair of binos will do, but I'm looking for that high mag power.

Inputs on glass quality and use with a tripod. Need a taller tripod, recomendaions on tripos welcomed.
