Oh wow, I forgot about the Ti-lock, now that is something I am intersted in, thank you for the suggestion.
I just returned a TiLock due to the fact that CRK does not want owners to disassemble them. I also didn't appreciate the fact that they ship it in the same box that the Sebenzas come in, except that they leave the wrench/ lube and locktite cutouts empty, (and don't even bother to include a note explaining why) . I really didn't like it that much anyway. The locking mechanism, while unique, wasn't all that fun to use. I had wanted one for a long time so it was quite a disappointment.
I don't blame you for disliking frame locks. They are everywhere. They pretty much all look the same on the Ti side. They are somewhat boring. At least linerlocks can be pretty on both sides.
For the price of a Sebenza/TiLock, around $400/$475, you can get some pretty nice midtechs and even some customs. I exchanged the TiLock for a custom that cost $10 more. The custom is nicer and much more fun than the CRK was. In fact, I like it better than any CRK I still own.
