Aren’t the 90/10 shocks adjustable? If so it has 80/20 and 70/30 settings which doesn’t mean much but you can at least slow the front end down a bit.
It’s damn near impossible to convince someone any shock that isn’t double adjustable is about worthless. Do guys go fast using them? Yes. But the assumption that’s a quick as it will go is a fallacy.
BTW, that’s the first I've heard that the 9 ways don’t adjust for rebound. If that’s true, then it would make more sense than what Calvert says on the phone, which is it changes bump and rebound at the same time. That makes no sense.
