Tornado Alley (PROG)

[rbtree]

Thanks. Yeah the ST Pro is one I've been directed too.

I have 2 relatively sturdy tripods, another 5 section leg unit that's OK, and a light one for trips more than a mile or three.... They're light, under 4-5 lb with any of my heads, and fine for even my big 500 f/4 II, 2x and body.... as long as there's no wind, stable at any shutter speed. But, were I to try 30 second exposures with a bigger lens (70-200) on a tracker, more beef would make sense.
