Hi. I was searching for some information ofnusing an Auralex Gramma Pad with the Mesa Subway stack. I too have the 112/115 stack and just wanted to see which padded you are using - is it the medium sized V2? Now that you have had it a while, do you find it makes a good improvement to your sound? I'm having some problems particularly in some bars and hotels where we play. Thanks for your time. Brian
