Green Rhino vs digitech cm-2

Im looking for a new od to try out. I love my bass VT2 and keeley tube screamer but, the the keeley loses too much low end and the VT gets compressed before I get enough grit. Im looking at the green rhino and cm-2 pedals but dont have any close by to try. I've got a voodoo labs sparkle drive mounted in my rack, and the new modded version at home which I like but, sometimes I want something alittle grittier that doesn't have a clean blend. The grit from a sparkle drive can get lost in a mix pretty easy even though it's pretty much my favorite. I like the bad monkey but, that pedal sucks some tone when disengaged. I was hoping to find something like it that doesn't have tone suck or low end drop. The green rhino looked like a good candidate and then I noticed the cm-2.
