Profilometer

anyone ever use a profilometer to fine tune their honing techniques, and consistency? Or do you prefer the trial and error method?
 
Not me . At 2700.00$ : my value benifit ratio is off the scale .
i just picked up a mitutoyo sj-210 for 1190.00. mint shape. I figured once i get a process nailed down ill sell it try to make my money back. I watched a video on youtube labeled "AERA super webinar - Keith jones on honing and cylinder finish". Great vid, you should go check it out. Puts alot of truth we cant see on a microscopic level, in visible perspective. Also gives some parameters for each application you should be trying to target. Maybe a little overboard, but ive had some hit and miss engines, and the only thing i have left to rule out, is cylinder finishing consistency.
