I disagree, the stock damper holes are a poor form of damping and they offered nearly zero on slow speed compression. Now it hits the valve and is correctly damped. I don't think I rode a single mile without bottoming the forks stock, and nearly every time I stopped hard they were blown thru.
If I require more flow to the valves, I can drill any combo of holes I want.
In high speed damping, I believe they were packing, or basically locking up as they couldn't flow enough as they moved so much on every strike. Now they stay up higher and I haven't had them stutter yet, but again, the road temps are only up to 50f at best right now so I'm not slamming the corners where I had this issue quite as hard.
