Mark iv & KT77's

Does anyone use KT77 tubes in the outer sockets here? I seen the set on eurotubes.com and im wondering what they sound like. If anyone knows please let me know before i spend some money.

I use them in the outer slots in my Mark III and I think they sound great. Smoother and thicker
than the El34's but you still get the added mid punch of an EL34 type tube.

thanks, so do you think they are an improvement from the 6L6?
