If you do choose to bring your main device it's a good idea to enable the "erase after x failed passcode attempts" option so that you can erase it without unlocking. Also instead of deleting your whole os you could just delete local data/apps but that may still be recoverable if they actually image the unallocated space. (Does anyone here know if that is the case with any popular tool?)
