The CST's are, or have the option of, Load Cells for the brakes don't they?
Taking that into account does a real hydraulic system really add much more, and surely it would be un-servo'd whilst most race cars will be servo based which is going to affect the feel? Who knows, it's unlikely I'll bother upgrading my G25 pedals for a good while yet
I'll admit I've not read much about the Frex pedals (read a bit about the wheel, do want), one downside with the Frex stuff does seem to be the support, seemingly down to the language barrier more than anything, at least the american option speaks something vaquely similar to english .
It's difficult to explain. At least, what I mean is I'm having difficulty.
With spring loaded pedals, all you have as resistance is the spring. Your brakes are still operated from 0-100% of motion. This means on spring loaded, if you are not on the pedal it is 0%, fully depressed is at 100%. It may be "tougher" to press it, but you still have to press it all the way to reach 100% braking.
On hydraulic pedals, you can increase the resistance of the fluid, so you actually change the axis range of the pedal - meaning I could (if I were inclined to do so) make it 100% braking at only 1% pedal motion.
