i dont like the idea of adding scales imho one of the main things i like about ti handles is that they are thin, adding G10 is gonna thicken them, if ya want G10 i say get a knife with G10 lol, YMMV though but again something i'd never do............unless i wanted thicker handles, anyway.
anodising? looks good on some but again it still scuffs and i dont know which looks better/worse, scuffed ti or scuffed ano lol??
i really like ti handles and have edc'd several (ie crawford kasper & perfigo & ti spyderco ATR) and scuffs is just something ya have to learn to live with, honestly the spyderco Ti ATR and the ti side of the EKI CQC12 (the '12 thats stonewashed anyway, not true on BB ones) hold up pretty well, both are stonewash, its the bead blast ti that scuffs easy.
but again, just something ya have to live with.
