As far as D, E or K, you really need to experiment with your rig and explore the tone. Justin on this forum really likes the D. I assume he like the D because he gets more break up at lower stage volumes. My preference on stage is two 8 ohm E's because my rig is able to create some clipping in the Es at reasonable stage volumes. I use a modded Twin into a McIntosh MC2100 amp configured as impedance mismatched upward versus the speaker load making the amp see less of a load and pushing more current to the speakers, (i.e., two 8 ohm Es wired in parallel to create 4 ohm load and connected to the 8 ohm leg). I also like in my home studio using one 8 ohm K connected to the 16 ohm leg and put in an isolation box so I can really turn it up--at high amplitude the K gets warmer. I used to use two Ks on stage but I've found that the Es are a bit warmer with my rig. They're just freaking heavy. But I now use a RockNRoller Multi-Cart and I just put my full rig and speaker cab on the cart and I can conveniently roll it on and off the stage (and keep it all on the cart)--when there's a ramp!
