Thanks, yep - I figure that a heavier mount is worth the extra $$ for stability and future proofing -- and besides, I'm a strong and still relatively young-and-fit lad, so no issues in moving it around.
I'm strongly tempted by the AZ-EQ6 GT because it will also be a terrific visual platform that would allow me to mount by C8 and 120'frac simultaneously when doing visual. I noted this example:

I guess I'd have to buy an additional mounting plate for that -- I assume it only comes with the one in the box.
But I'm definitely still open to other advice -- experience by users trumps hype.
