I don't fasten my seat to the bike anymore. If it goes flying off when I'm going down the road, I have other, more pressing issues that will make losing the seat seem minor. The bike has been around the block a few times. The seat has never come up to meet me on my way down. I've tried a few knurled thumb screw types to use on the side panels, without much success. Either my fingers can't manipulate them, or or they stick out and I "catch" on them. I do understand your desire to make the seat "quick release". I have a Concours that has a key operated, one turn release on the seat, and quick release pins on the gas tank. I can have that bike down to the backbone in minutes.
