the frame and cups and just any feedback on wheels manufacturing ones would be much appreciated although guessing they're decent.

I think the Park Tools page recommends grease if the frame is aluminium, not if it's carbon. They didn't say what to do if it's steel or titanium.

Oh bugger, yeah forgot to say, it's a Ti frame that it's going on.

I'm guessing a liberal amount of marine grease or the like would help.

From Wheels Manufacturing;

<div>Thoroughly clean the bottom bracket shell. Apply a thin layer of high quality grease, PTFE or anti-seize compound to mating surfaces before installation. Use the correct compound for your BB shell material!</div>

I thought the general rule of thumb was: if you want it out again, the grease it, if you want it to stay put, then no grease?

Surely it depends on what the cups are made of?
