I know Tricks of the Trade are supposed to be to give your tank a little extra aggro but it also adds damage to the target. A lot of times I just share with a fellow rogue in the raid by setting up a cool macro either Falien or Phel told me... don't remember who but I figured I would post it here so that up and coming raid rogues would know about it. The macro is as follows:
/tar (name of rogue/tank you want to target)
/cast tricks of the trade
/targetlasttargetJust a nice way to not really break your rotation up much and with the updated macro system it shows when it refreshes without you having to put a bunch of extra crap in there

With the last line in there you don't ever have to leave the mob you are pounding on you just click that macro it will go and pop it on whoever the target is in the macro so you could essentially boost the deeps of most anyone. If you inform the other rogue of the same macro (although this is a somewhat common macro) you can trade with them

Enjoy!
