Although it's not technically a "flipper," any of benchmade's "axis" lock knives can be deployed quickly with the index finger on the off-side. Worth fondling, anyhow, to see how it fits your hand. The bonus is that the same function locks the knife, instead of having a separate safety. I don't do liner-locks, and the "lawyer lock" on the kershaws has always been awkward to me. Just my $.02.
