ChasingRichard once bubbled...
They instructors tried to feed me that when I got certified. Its a load of crap. I used paddle fins once and never again. When I first started I found a lot of old timers like you. The younger divers with borrow my fins and ask me where they could buy some. It's just like when I started snowboarding with all the skiers complaining about me ruining the mountain.
Split fins are the best thing to happen to scuba in 20 years.
Bold talk for a new diver. Perhaps you could contrast the performance of the splits vs the paddle when performing various kicks for us? Maybe examine the frog, modified frog, reverse frog, modified flutter, shuffle and flutter.
Let me guess you only flutter right? You read Rodale's don't ya? If your ever in my neck of the woods look me up I'll show you what I mean, no charge.
