Do I use too many commas?

'sideplay adjustability' sounds like a nice way of saying really poor tolerances so that it'll either have too much sticktion to work well, or will be clunking from side to side annoyingly.
Much like my Softride stem...
I tried one and am not red-hot about it but YMMV. I'm a near-Clyde [Missouri Mule [Momma was a Clyde], maybe] at 188 pounds and at the 'lightest' tension, I have difficulty determining if I am actually compressing the blessed spring even when doing some rough stuff. It's on my Beater-Sunday-Java-Sortie-Steed for the time being. [Yes, I have too many bikes and don't know what to do about it. No, I have no plans to get rid of her.] Note carefully the caveat about adjusting the spring.
