My 2 cents:
I'm a so-called "sprinter" (but if you saw me race you'd wonder...)
For me, logging max speed and cadence in training and racing is important. Having a file from a training or race day is great for analysis...IF you analyze it.
As Mark and Brawlo say, don't look at it in a race. Head up. Use it as a logging tool.
I recently got into a heated discussion from an accomplished veteran racer who had "logs dating back 20 years...". He tried to convince me to keep paper journals of my workouts and details from the efforts. I'd watch him scribble notes after every training effort. I told him that my SRM was better. He got pissed. He rattled off some soft stats from a workout. Then I countered that I could tell him my EXACT distance, average speed, max speed, average power, max power, average cadence, max cadence, average HR, max HR, rough splits, and atmospheric temperature from EVERY effort (race or training) that I've done since I got the device. I think I won that argument
The Garmin 500 and PowerTap Cervo gives you all of that great data without power if you don't have power meter cranks. That is still a LOT of data. One tip about Garmin systems, don't let it use the satellite to track your speed. This is great for long road rides where the average is more important, but this isn't as accurate as having a sensor on the wheel.
The combo speed/cadence sensors can be hairy sometimes because as you change gear ratios, your rear wheel will move in and out of the rear dropout, unlike a road bike where the wheel is always in the same position. So, when you change gears on the track bike you might have to move the magnet...and REMEMBER to move the magnet. But there is an easy solution: Get individual ANT+ Speed and Cadence sensors. Put the speed on the fork to pick up from the front wheel and put the cadence sensor on the chainstay to pickup from the crank arm. Your front wheel and cranks will always be in the same spot
