Anybody else notice this?

I have been using my new HB Sport for the past month and it made a quick shave even more so. The only problem I've been having is  the back of my head when I went against the grain, I didn't think the shave was as close as the classic.

Today I used my HB Sport with Sensor doubles on the top/ sides on my head then I used my classic with an Atra blade on the back. Results where awsome. I guess the whells didn't allow me to navigate the contour of my head as well the original version.

Guess I'm using two HeadBlades in the shower now.

I can't shave the back of my head with my HB Sport and atra blades either.  I go with the grain with the HB and against with my M3 or Fusion Power.  If the HB classic works better on the back, I may have to get one.

I use the HB Classic.  I first go with the grain over my whole head/neck and then against the grain on just the back of my head, excluding my neck.  This seems to give me the closest, smoothest shave.  I use the Atra Plus blades on the HB Classic.
