I know for sure I'm going

Right now I'm running it through an avatar 2x12 with a Vintage 30 and a G12H30.  Togther the combo is a little on the bright side for my taste (super tinny highs).  And it feels like some mids are missing.  There is also a lack of bottom end. 

I'm looking for something warm like the ET65, but I'm not sure what to pair it with?  Huge bottom is a must and I don't want to completely filter out the highs I just want to tame them in a warm fashion, but still sound open.  Too much to ask?

I know for sure I'm going with a ET65.  I'm just torn between the reaper HP and the reaper 55HZ. 

My main concern is HUGE low end and I'm sure even with the 55HZ with my amp I can dial the high end back in.

What's the better choice?

This is just me ... I generally always like the regular Reaper (30-watt or HP) better than the 55 ... BUT, I've just started gigging with a vintage Bandmaster (also a very bright amp) and I made a 1/3 open back for the vintage small (for a Bandmaster) 2x12 Cab ... and I'm running it with one reg Reaper and one Reaper 55 ... and it's just PERFECT!  sooo ... maybe I need to start rethinking my stance!
