I go from shorty to drysuit. Lake Belton get to 53 degrees at the coldest I've seen. A really good 3/2 wetsuit will work fine. ONLY look at wetsuits that have seams that say taped and sealed. NEVER buy a glued and stitched (aka: "flatlock") wetsuit...they suck in comparison and, in my opinion, are the cheap way out. Glues and stitched seams allow the cold water to immediately flush into the wetsuit making you cold for a while. The taped and sealed wetsuits DO NOT allow any flushing of water so you are much warmer and dryer inside even though it's a wetsuit. There's only 2 full wetsuits I would own, the Xcel 3/2 Infinity Drylock (I have their long sleeve shorty) or the O'Neil Psycho Freak 3.5/2.5. Drysuits are easier to get in and out of, you stay dry inside, and when you're resting between sets you come out of the drysuit dry and can just put on a light jacket and jeans easily. Plus, I just wear a breathable long sleeve Underamor top and boardshorts in my drysuit and I'm still hot inside it after only a few minutes of surfing. Drysuits though you need to be cautious not to rip the cuffs/seams on the wrists or ankles getting in or out. Multiple people can wear the same drysuit, wetsuits are not good to share because sizing is critical for a wetsuit to work, plus no one wants to get in a wetsuit that cold and wet already and that's kind of gross anyways. Texas Malibu can install the heater if you want.
