Chris, There are many good routes up there! The 6 you may be referring to is in the center of the cliff. There is a semi bolted green slab that leads up to an anchor then a very sharp 5.6 crack that leads to the top. There are also alot of other climbs there that are more than worth it to jump on. I guarantee that you will be able to get up anything you find. I really like the 5.9? about 50 feet to the left of the 5.6 I mentioned. There are also some fantastic 5.7's to the right that are also awesome!!! Dont worry about Paul Cormiers home made bolt hangers, I havent tested them, but they look solid!!!!
Have a great time on your adventure!!!!
Btw, It is easier to hike down to the base of the cliff if you follow an easy groove down and to the right/middle of the top of the cliff (looking out).
