In reply to gardening: New Mystique is 5 clips. The Directissima is 6 clips. Most routes are 6-10 but a few require more and it is common to extend awkward clips with daisy chains. You will also want to take a couple extra for the belays. So, 10-14 in total will see you OK.
The two routes that you mention plus Open Road/Highway 395 are the best of the grade 6 routes there but these tend to be used by virtually everyone as warm-ups so be prepared to share.
