I was under the impression that by using that particular analogy, you were implying that it was a bad idea since it would mean taking one brand and using it within another. If I misread that, then my mistake and I sincerely apologize.
While this is something to consider, I don't think it's completely accurate. I've read posts of people who prefer the flipper because of arthritis issues. I do agree that a well made choil can secure the hand from slipping on the blade. I also imagine that a flipper on top of that would do much better. Might very well be overkill though (I am a huge fan of choils BTW). And no one can deny that a quality folder with a flipper has a market.
