Micromatics, from aggressive to mild are... OCMM > Clog Pruf > Flying Wing (Bullet Tip) Again, I've not used the Flying Wing but I've read multiple times that it's the mildest of the 3. Why, I have no idea. Maybe HT can stop by and shed some more light on the subject.
Last week I saw one that was unusual (to me). Not sure which tip but it was nickel and had the non-flat angled face and right in the center it was stamped Hold Flat Against Face. I wanna say it was OC but not sure. Sound familiar?
