I want to participate in track days, but that involves investing in a good roadracing suit. I've never owned one, so I have a few questions.
At this point I am leaning towards a special order through Syed Leathers. They are custom made using approx. 25 measurements.

I am definitely open to other options.

My primary question is: one piece, or two? What are the pros and cons of each?
Other questions: Snaps or Velcro? Ventilation or not? Beaded or Mandarin collar?
I intend to go with the full protection package, but there are additional options that I am unsure about: Back protector, Neck Protector / Hump, Knee Sliders?

Anybodies input or opinion would be greatly appreciated!
