so...i had a long distortion quest and finally found the few pedals that did everything for me:
SLOstrortion is amazingly good, the DLS Mk2.2 is also really good and finally the EQD Monarch is great, especially pushed by the DLS.
I've had Rat, Fullbore (which i really hated), Way Huge Fat Sandwich, EXH Metal Muff, Distortion III...and a number of others that i cant remember, but i have to say these three are the best i have come across. I will say there is one pedal that is on my list, the MXR Badass 78...it does sound really good, i tried in a shop and didn't buy it because i was looking for more of an OD pedal...you should give it a go just for a different flavor.
also to Skip's point on the BAT front, when i was ordering my pedal last month, Mark did mention that his working on some stuff, so maybe hold off until you see what he comes up with.
