I appreciate the concern, but I'm OK if some get passed over. I'd much rather that than have someone come up to me and go "hey, you've got X bass, don't you?" and I'm "ahh yeah, sorry, I left it at home - maybe next year, if I still own it by then!"
I've already decided to rein things in slightly - I'm not going to take the extra 1x12 cab. Going to take the Markbass combo and the TC Electronic BH250 head as a headphones only amp - which might be handy if things get loud in the room anyway.
