I too am currently working on my commercial. I started when I had about 175 hours and now I am at about 230. I will do the last 15-20 hammering out the maneuvers so its fresh at checkride time. I'd like to take the checkride as close to 250 as possible. What I decided to do was to build my time as cross country time. I figured that if I needed 75 hours I could either bore holes in the sky 1 hour at a time or go fun places with friends and family. The time building went a lot faster and I discovered a love of flying that had disappeared during all those hours under the hood during instrument training.

Good luck with your training.
