TQ'd, won, and set a new personal best at the track today. I've basically been running EA's Snowbirds setup but with a front spool and some minor fluid changes. I feel like it is the best 17.5/stock carpet setup to begin with. If you need a starting point USE IT. The setup is also good in mod with just a spring and droop change. We've also had great luck with the setup in VTA with 2.9/2.7 springs.
In other words, there's a reason it won Snowbirds
