I've ridden with these guys once, and based off of that limited experience you would be fine. I'm sure they get into more technical stuff, but seems like their normal routine would be fine for you, if you are ok with the rougher county roads that Texas has to offer.

Up the road a bit, but a bunch of guys from Austin are coming up. Anyone is invited if you want to come meet some people
