I use an electronic drum kit at home and love it. Quiet to play on. I have multiple drum kit sounds at the touch of a button. Takes up far less space than an acoustic kit.
Back in my playing days I always carried some extra equipment. Spare bass drum pedal, extra snare drum ( never know when a head is gonna let go ), and a couple extra cymbals. Usually an ext r a ride and a set of hi-hats. Playing mostly hard rock and metal can really take a toll on equipment.
I also think if you go into a place and leave just because you see an electronic kit is foolish. I'm not a huge f an of them for live shows but I've seen some guys play great shows using electronic kits. If the P.A. can handle an E-kit, they can sound amazing.
