Anaconda No-Gi Forum >> standing -- how to get an overhook?

Are there any particular steps or strategies to take in order to get a nice deep overhook ... or do I just have to be patient and wait for my opponent to decide he wants an underhook?

I've never done formal wrestling, but have been doing Judo for 10 years. right handed. I have done a fair bit of no-gi ground grappling, and a small amount of no-gi standup grappling, which is what I'm interested in. I absolutely nailed what we'd call yoko-wakare in Judo. What is it properly called in wrestling? Here is a vid of Shonie Carter teaching it for no-gi.

My problem is the first step, getting a nice neep overhook. I found myself engaged in an awful lot of 'feeling out', 'handfighting' (?), shucking off neck/head grips, etc. Until finally I got lucky, and found myself with a good overhook. Surely there must be a better way?

thanks!
