Best launch & fishing area off the Chagrin River?

[AM]

I'm planning on fishing off of the Chagrin River area this weekend for the first time. Any suggestions on the best ramp to use? The plan is to troll for walleye in 55-65 ft. until the kids get bored then move in for smallmouth. If you can offer any numbers or suggestions on where to go it will be greatly appreciated and I'll post results Sunday night.

Thanks for the help.
