This, IMO. I don't like metal grips or scales. I'm not mad on slippery polymers either.
One thing to consider, plastics do get brittle in the very cold. If you drop the knife, you could have issues. If you get polymer/composite scales be sure they are readily replaceable, just IMO. I have seen fibre reinforced plastic shatter.
Also, if you have to use it to gut, eh... don't get very white plastics. I'll grant a lot of plastics are very stain resistant but the ones with textures, well, you gotta clean 'em. I don't mind scratched up or patinaed knives, they add character, but I dislike, absolutely dislike caked blood on knives, and getting rid of blood from these crevices. Arguably, on a folder, you're screwed no matter what scales you get, it's a folder, blood will get into the crevices, you can just used your fixed blade instead.
OTOH, I think Ti looks really cool, if you were going for the high end look, Ti all the way.
Do you have the option of buying Ti scales and switching to composite later if you don't like the feel? That may be the best way to reconcile first kinda cool with second kinda cool.
