Used one with a Heritage SVT-CL once...loved it. Was not far off of what an 810e sounds like IMHO.
Hartke makes nice stuff, too. Should be fine with that cab.
Yeah, this is my first ampeg cab and so far loving it. I will be upgrading the Hartke at some point, it may be an ampeg of sort or maybe a darkglass.
I know you are an ampeg kind of guy, between the 7-pro and the 3-pro, which way would you go? I play mostly modern progressive rock and I use some distortion at times and sometimes use effects for some extra layers in the higher registers
