Thanks for the info guys, I'll definitely be perusing it tonight. I run HL steel boxes because they are so quiet, sexy smooth and show no signs of wear in my other tanks. This time I'm trying the new steel 3:1's since the KV really needs the torque to drag it's 13lb ass around. The boxes are in the mail now and I hope the live up to the quality of the regular steel ones.
God I love every aspect of this hobby.
