I was going to post in the vendor section, but I'm not technically a vendor. Just wanted to share that I had a custom suit made by Specialized Racing Gear - David Gonzales - number 550 and it turned out really well. Best fit I've ever had and surprisingly (to me) is much lighter than my existing Taichi Suit. I found that Taichi Suits feel great and have great ventilation, but don't hold up well in a crash.
I had a lot of vented leather put into this, as well as a camelbak and elbow sliders, but was given a lot of choice in how I wanted "my" suit to be made.
