Roll Shaping

I am interested in improving my roll shaping skills. This is a very basic sourdough formula of about 67% hydration, bulk fermented for about 3 and a quarter hours in a warm city kitchen, then shaped and proofed for about another hour and a quarter, baked with steam.

I tried some fendus, which, while they had the right shape, were rather bloated for my taste. I prefer the slimmer shape, with a nice point for rolls. I think this will require a wider "hinge" and a narrower body.

I also tried a shape I believe I saw here, although I am not sure. A dowel is pressed into the side of a round roll and a flap is rolled. This flap is then pulled over the top of the roll, making a lovely effect. If this sounds familiar to anyone, I'd appreciate some guidance.

The rolls shown, in a "teardrop" shape, are, as far as I can tell, an original idea, cut to a point with a bench knife from a round shape that has been lengthened a little. People seem to have fun eating them.

Additional discussion about rolls, especially shaping, would be welcomed.

I'm including an additional crumb shot of the batard just because I like the picture.
