Bladerunner,
I'm personally not a fan of the clipper kit, not because of what it looks like but because bodykits are often fitted to hide dodgy bits of rust/accident damage. It's only a resale thing, so if you plan on keeping the car forever (like many on here) then do what you want. Look at Adam's for example, it looks great with the kit on (looks better in the flesh) and in Red would probably look wrong without the bodykit. My ragtop is one of those bizarre brown/burgendy types that would look stupid with a clipper kit.
Besides, if it slows you down too much you've then got a good excuse to put something a little bigger under the bonnet.
