I have b14's with the fronts re-valved and can tell you that they do feel great compared to my previous HKS SP's (too stiff for DD). Handling was great (not too much different from the HKS but this is comparing it on spirited runs). I did buy mines 2nd hand from an old member off the forums.
He has a link to the different combinations and setups he tried with the B14 listed here:

When I got it from him, it had the 6k springs on it with the group N top hats and STI rear top hats on. Also gave me the 5k springs and the stock progressive springs with it. I swapped it out to the 5k springs and changed out the top hats for RS CasCams but eventually went back to the Group N + 2 camber bolts due to the NVH (eventually car became my DD again). Also had camber slippage issues with the CasCams (camber would slip to full negative on hard corners, probably either due to bottoming out/the spring rate).
Also there is a link that talks a lot about modifying the bilstein suspension:
