Tube rolling suggestions


I purchased a Rogue M150 several months ago (my first tube gear). I would like to try some tube rolling and have a few questions I could use some help with. Which tubes have the greatest affect on the sound of the amp Input, Driver or Output? Any suggestions regarding replacement tubes and their characteristics will be appreciated? The stock tubes in each mono block are all Electro Harmonix, drivers are (2) 12AU7, input is (1) 12 AX7, Output are (4) KT88.
Thanks in Advance

FWIW. I got more satisfaction out of fiddling with interconnects between my Zeus and pre-amp than I did out of tube swapping. As the 12ax7's are long lived, cost of replacing your favorite NOS is no big deal I reckon, but I liked the idea of finding a cable that worked well with the relatively cheap current production tubes and found contentment that way. The limited amount of tube swapping I did always got me 'different and better than the other in some ways on some source material' but never 'just plain better'. Good luck!
