Hi,

welcome to BF, first of all!

I can't really comment on the three tripods mentioned as I don't know any of them. From the specs all look very capable with their 20kg+ max load - in my opinion they're slightly over the top...

Hi,

haven't found any reviews for the 501 yet and I just had some quick looks through it at a show - not really enough for a review.

Hi,

the 500AH is actually a lot sturdier than the 128RC - strange enough it's the ame weight. I like mine a lot with a full size scope on it.
