IO540,
It's all a matter of personal preference, but 2000ft above a ridge with 30knts winds could turn into a wild ride. 20knts @ 2000ft above would be about what this old pussy would want, some say clear the tops by 1000ft for every 10knots of wind. I've crossed many a 10000ft ridge by 50ft on a cold & smooth day, which are wonderful to fly in.
Also be wary of any shear in forecast winds aloft, i.e. the winds at 12000 ft are different from those at 15000ft.
Most important of all, always have an out. That's the second and third most important things too. And probably fourth and fifth.
