I would start out with the OG VapCap and see how you like it. They all operate about the same. The only benefit to getting the Ti Glassy or Woodie is that you can change out the bodies and use the same bowl for all body styles. Hope that came out somewhat clearly.
There is also very minor performance changes/differences with all models with a TI tip vs glass OG style. The amount of airflow and resistance into the cap changes things enough to change the overall results.
That said, i agree with MC79. Get the basic model, and if you like it you can always get another order later. The differences in performance are very minor, and it certainly could be possible for someone to prefer the OG glass to the TI because they simply are diffrent.
