Speaking of the 300SN I would really like to see a picture of the blade to see how the heck it works, I posted a few days ago in the BM forum but didn't get a single reply and I've looked threw pages and pages of google images to no avail. I'm sure it can be done (because of the 300SN) but I can't envision how its set up.
I don't remember who but just recently someone here made himself new omega springs for his Adams out of keychain ring wire and said it was about 2x as strong as the factory ones. Increasing the omega spring wire diameter is all it takes to increase the detent strength on an axis lock. For a CBBL it would be even easier as it's just a single coil spring.
Another point to bring up, the flipper doesn't have to be permanently attached to the blade, look at the Kershaw OD 1&2, that sort of device could be used to not interfere with the BBL/CBBL.
