I need to replace some tip tops. A couple due to breakage, a couple due to braid wearing through. What are some good guides for braid? One of them is a micro guide although im going to oversize it because my leader caused insert to pop out and now its grooved.

SIC rings, in Fuji would be most likely LG.

Any ceramic guide will hold up to braid, it has no abrasive qualities, the dirt and grit you put in the line does that is what grooved your soft no insert tip top. Ceramics will hold up to any line

A good quality tip top from Fuji, American Tackle etc of a size to match the running guides will solve your problem. No way would a knot displace an insert. The tip may have had an impact of some sort.
