The learning curve for clips and straps is similar to clipless. You just ride the underside of the pedals unitl you can flip them using the little tab. I try to keep my straps at a tight enough tension where I can easily slip in or out with my trusty Sambas or whatever else shoe I have. The only thing I don't like about clips and straps is the small loss of pull on the upstroke that you get with clipless pedals.

Yes, I ride with cages as well. My WTB pedals have a flip tab which is nice. If I'm not feeling comfortable with them on a particular day (or maybe after the bar) then I just ride on the platform.

I actually don't have the nylon strap right now. I figure I'll put them back on, but I don't really do major track standing or wicked barspinz so what evz.

I did this the very first day I had a bike with clips. This was thirty years ago. I haven't sone it since. Toe clips don't take long to get used to. I still use them. I still use the Avocet cycling shoes I bought 30 years ago, as well. No clipless for me

I run MKS Sylvan track pedals with plastic clips and synthetic straps. These particular pedals have a tab on them so you can flip the pedal over. You get used to it pretty quick. I keep my straps kind of loose so it's real easy to get in and out of them and still prevents my feet from slipping off the pedals. This set-up also allows me to wear different kinds of shoes.
