I really like mine. I haven't had a chance to use them on OH on a REALLY nice kit yet, but on all the kits and acoustics I have tried them on, they've pleased me every time. They take a little more effort to place than mics with wider polar patterns (such as the SP B1 and the MXL 603) but this is no different to most SDCs. Having used mine, a drummer friend who is getting into session work got a pair (which he finally got his hands on last night), so I can let you know how he finds them.
Be aware that they are not technically matched pairs - they are consecutively-numbered mics, made one after the other on the line. I haven't heard a difference between mine, and I haven't read about anyone else having noticed anything either, but you should just know that they are not strictly matched.
Hope that helps,
Nik
