I did not vote on the poll, there are too many factors keeping me from choosing just one. Here is my input, though (not intended to offend anyone):
Setup for pure speed is great, only if it does not compromise comfort. I prefer the best comfort that will allow me to still take the big hits on the track. I would prefer to enjoy hours of riding rather than short bursts of speed. Track time increases speed, anyway, so you get the best of both in the long run. Depending on the conditions, this will be different for different racers. If comfort is a sacrifice, then MX racers probably want a setup that will wear them out about the same time they hit the finish line. Enduro and HS racers would probably prefer something a bit more plush for the long haul.
IMHO, trickness is a non-issue. I actually prefer a "sleeper".
Economics is a big issue for me, and probably most of the riding public. Unless someone else foots the bill, I think everyone is looking for the best "bang for the buck". Many times this is a compromise, but IMHO, if you spend top dollar you should expect to get the very best. Another thing I look for is the durability of the product. If you go for the cheapest price on a suspension setup that works for you, it may turn out great. But if the parts dont last and the suspension goes crappy quickly, then the mod was not worth the money.
And last but not least, there are two other items that many racers would demand. First, and foremost, quality of workmanship. I dont want some careless guy who calls himself a mechanic touching my suspension and screwing it up. No racer wants to have his new suspension torn down to fix a problem caused by negligence. This just wasts track and setup time. Second, I think turnaround time is very important. Not really an issue with me (since I live in Japan and cannot really expect anything to get back to me quickly from the US), but I have had issues in the past with parts taking months to get to me when I was in the US. I think this issue can easily be addressed by the suspension company giving an accurate statement of turnaround time at the time of the suspension order. In other words, avoid negative surprises.
