Recently replaced my XM2 with CC6. CC6 was quiet, also because it was new, compared to the season XM2. But I noticed a serious issue while driving on highway. At 80km/h was still fine, as I go higher, I thought I was getting hit by crosswind. The grip was problematic at that speed. There were dry and damp area throughout, but I never felt that on my XM2, even when it was already seasoned.

Not recommended for people that travel a lot on that speed range.
