OK. I just thought with 24 studs being affected, the large increase in polygons
may be a bad idea, but it's better to get it right.

AFAIK this part is only available in black, but better safe than sorry.

You mean inline the stud2a, then inline a cylinder under it and trim that?

Well yes and no - that sentence actually asked 2 different questions :) but both
will be solved if I inline the studs and trim the cylinders as Orion suggested
(I think).
Thanks for your help guys! (Even if it means more work for me...)
