is it your experience that the venting doesn't matter as much as just having more mass?

Venting is the same internally. Every mfg. has their own little version of better but as long as they have some form of curved internal venting you're good.
Less mass is great, but now now you need to add cooling, the faster heating and cooling stresses out more components, higher peak temps, and on top of that more money. If your racing then yeah none of that matters, for an extra .2 seconds or whatever, could mean a position. I'd see that money better spent on another track weekend (more seat time), 18" wheels (less weight, lower costs, more selection), aero, data analysis, etc. If replacements were more inline with 1 piece rotors I could see the benefit but, to me it's a money sink within a money sink.
