ggk,
I use the Honigs B-8 combo pleated pants and love them. I am bigger than you at 6'- 220, but I have plenty of room to work the plate in these pants. The nice thing about buying equipment from Honigs is the fact that they readily accept returns on equipment or apparrel that you haven't used.
You can access them online at:

Good luck!
Tim.
