I have the bolstered micarta ATCF and it feels perfect in my hand - I prefer the its feel over the full ti handled version. But keep in mind, in some ways it is almost an entirely different knife. If you want slim profile & lighter weight, the Ti handled ATCF is the better choice. On the other hand, the bolstered version is a heftier knife, the micarta scales have palm swells, and it is more attractive (and more expensive).
Ultimately, it would be best to handle different models before you make any decisions. Good luck!
