Looking at getting a new camera before I go to the Alps this year..

I’ve narrowed my choices down to the Stealth 2 or the Ghost S, the Stealth is much smaller and lighter but will only record at 1080 30fps, 720 60fps, whereas the Ghost S records at 1080 60fps, 720 120fps..

I’d like to go for the lighter weight, but will I really notice the difference in recording 720 60pfs vs 1080 60fps?

Cheers
