It's slim, but I have no problems with it. Some flippers are meant to be accompanied by a flick though. The flipper in the storm just overcomes the detent really until you master it (like the small M16, I did eventually get the thing just right to open it flipper only, no flick). Flippers are fun, and I prefer them, but once you learn a small variety of inertia deployment methods they become superfluous.
That said, they're still fun, and they're more accessable since there's basically no learning curve. But there is a benefit to them that isn't as often cited, which is that in lock failure situations the flipper will close on your finger before the blade does, which isn't ideal but is nonetheless a better failure scenario.
I'm going to give a Kershaw RAM a try at some point and see how that fairs.
Reflecting on the whole flipper/AO thing, it kinds of seems that slipjoints and lockbacks are really the only kinds of knives that could even make practical use of it. Any good liner lock, BB lock, axis lock, compression lock etc with a smooth action is going to be easily flickable with just a thumbstud/spyderhole, and if you have a lock that can be disengaged before the flick (axis locks for example, compression locks too) you can remove basically any resistance to the opening anyway. Beyond this, any of these knives can be more quickly deployed with inertia techniques anyway.
