I use the BB and a TS for modules that don't have a ton of gain on the channel to begin with (BMAN/VX Channel A/etc.). However, if you are trying to boost a module like EG5/SL2X/SL Channel B/etc. and you already have a good amount of gain, then using a boost pedal to drive it further is just going to give you a ton of feedback and not much else. I thought I might be able to use the BB as a boost for channel A on some of my higher gain channels to do solos and what not, but it just makes things to noisey and lots of feedback so I'm sticking with just using channel B for boost on those. If anyone else has been able to use a BB or whatever to boost the higher gain modules and they don't get this kind of situation, I'd love to hear your settings....
