Yes - - those are actually my cranks, too - among the first of Big M's "Charlies."
I'm a big fan of tight action....and not just tight, but "lively" action. Think high-frequency wiggles. When I'm fishing in cover (and in general), these characteristics give the bait a quick start-up.....in other words, more wiggles per distance pulled.
It's the action I find most consistent, whether the water is clear or not.
I was working on a few designs to try to nail the action I was looking for (just for personal fun) last year. I'm pretty happy with the results, but I never really got them totally past the prototype phase.
Making your own cranks is fun, but really time consuming. I haven't messed around with it since I started going back to school, but I want to get back around to it again one day.
