I'm in the same boat jdh3000 and thinking different Rumble possibilities over.
I'm either getting a 500 combo + cab, or an 800HD and 2 cabs. My only issue is trying to crunch the possibilities regarding having a backup rig and things I may mix and match with.
For me, I reckon an 800HD and two 2x10 Rumble cabs would be a good modular option with an additional head tucked away as a backup - not necessaily another 800HD - just something to get me by.
My other option would be a 500 combo and Rumble 2x10 cab with the backup head, say...a 800HD so I can go 400w into the 2x10 cab if the 500 combo should fail. If the 2x10 cab fails (how likely is this?), then I have the 350w of the Rumble 500 combo and its DI to fall back on. You're probably wondering, why a backup 800HD and not a 2nd hand 500HD or a Trace Elliot Elf? Because if I add another cab, I have lots of options then and can use the 2 cabs with 800w of the 800HD as my main rig. However, I'm now acutely aware that the latter GAS situation would require a backup-backup head (because I made my backup my main) or dragging the 500 combo around as a backup. I'm just being a greedy git now though - albeit still a bit practical.
What do you experienced Rumblers think of my two potential options above? It would be great to get folks' opinions here in terms of Rumble gear combinations in context of backup rig considerations/recommendations.
I also have an Ampeg SCR-DI and Sansamp Bass Driver which could go to a PA (if a PA is available).
