My rail game is weak, so I'm not a big fan of rails.
I suck at tranny, but I still love carving around and trying the best I can. I get bored of mini ramps quite easily though (I'm probably gonna catch some hate for saying that one, hah). It's just that it's a lot going back and forth only and I have such a limited number of tricks for it. I could imagine if I had a bigger bag of tricks it'd be way more fun to skate.
Also, like someone above said, my pop game ain't the best these days, so anytime someone wants to go skate a spot and it's like a waist high ledge or Manny pad I have a hard time skating it and get bummed, ahah. I'll drag my ass to the nearest red curb.
I love stairs, but anything over a five or a six doesn't appeal to me much these days. Every now and then on a rare occasion I'll get the urge to throw down, but I keep it on the mellower side these days when it comes to stairs.
Other than that though, I'm game to skate whatever. My favorites are Manny pads and banks.
