I like the griffin ceramic in saltwater length for everything size 14 and up.

For smaller stuff I like the renzetti midge size saltwater length. It has a synthetic ruby insert in the tip to protect the thread. The thin tip will go through the gap of hooks all the way down to size 18. The feet are teflon and allow the spool to glide very smoothly, but you can still increase tension by squeezing the whole thing. I wouldn't dare use another bobbin with 10/0 thread.
