I have two different styles of burners on my Brutus, all high pressure. One banjo burner like the one pictured and two standard jet style burners. The Banjo burner is under my HLT and the other two under the boil and mash tun. So far the combo of the three burners has worked great. I used the Banjo under the hlt so I can heat up my water quickly. The mash and boil really don't need massive burners - you don't want to burn your mash, and once you transfer to your boil kettle your wort should already be fairly hot.
I will be making one mod, and post the advice for everyone here... Do not remove the adjustable air damper on the burners. It is not dangerous, just makes for a crappy burn. Someone at my local LHBS told me they were not necessary, so I left them off when I put my system together. Now I'm taking things apart to put them on.
