Yeah, same here. I can be a bit blunt, but we are all in the same boat. Sorry about that. My point in my first post was that debates over the IMS options get ugly quick and I (and most here) prefer to keep things light and avoid confrontation...which I failed at miserably in this thread, haha
That's a beautiful 987 and don't feel like you aren't welcome here. The 986 and 987 are still very similar and there are plenty of guys here with the 987, so plenty of help and discussion to be had.
FWIW, I think the roller bearing is superior to any single row ball bearing, ceramic hybrid or not. However, if I replaced my double row bearing, I'd probably favor a double row ceramic hybrid ball bearing over roller.
Single - roller bearing.
Double - ceramic hybrid ball bearing.
