I agree with TS&M. If I could get my fins on easily, they were too loose and often came loose as I did my giant stride (fortunately they were positively buoyant). If they were tight enough to not come loose upon entry, I had trouble getting them off at the end of the dive. When I got my new Jetfins, I knew I couldn't risk losing one on entry since it would sink like a brick, so I went with the spring straps that have the rubber cover/tab. They not only made putting them on a snap, but taking them off is just as easy and they were super comfortable while diving. I'll never go back to rubber straps.
