I'm loving this thread... Reminds me of my own self-contained irony - I put in endless effort to make my Tamas sing as much as possible, AAX cymbals (my preference), racks/stands placing my cymbals within 1/4" tolerances, toms with 1/2" separation, etc... And I, too, sometimes use the house kit, bring my pedals and sticks, and bang away.
However, these places make their crappy house kits sometimes make them sound REALLY good (simply because of the time spent on mixing/mic'ing, etc...). What we hear and what others hear are often 2 vastly different things. Often, when asked to play the house kit, I'll ask for them to do a sound check for me (instead of the other way around) with me at FOH.
