I use the PH610 cab and I absolutely love it! It really does have the grapes and about as much as a 810 in a smaller size and weight. I did the two 410 cab setup years ago and although it was nice to have the options of using one or both depending on gig, it was actually more of a pain to travel with, load in and setup. Now with the 610 I just tilt it back and wheel it in, set my amp on top and hook everything up and I am good to go. If I were you I would stay with the 610 or if you really want a 810 why not get one? The two 410's stacked would be about as big as a 810 anyways wouldn't it?
