For what it's worth, here's my general approach to route planning: I will generally look at my objectives (peak, campsite, view point, or what have you). If there's a trail that serves well, of course I'll use the trail. However, if the trail takes a roundabout route, I may opt to take an XC route (factoring in conditions and the fact that XC travel is generally slower than trail travel). I generally use the trails as much as possible, trying to reduce my XC travel in areas served by trails. However if there's some obvious XC route that will save significant time, I may take it.
In the case of San Jac, I will sometimes follow the Sid Davis drainage up to the Tamarack camp area, passing through the large bowl like area above Tamarack, and heading towards San Jac peak but cutting slightly south, I join a long abandoned trail which connects to the main trail coming in from Wellman Divide. I'll take the main trail to the Miller-San Jac saddle, cutting cross country for the last little bit to the saddle. From the saddle, I'll basically follow the ridge up. Counterintuitively, I found that staying slightly on the N side of the crest of the ridge was the best route (indeed there were the remains of an old trail). From the summit, I descended the long ridge down to the saddle between Folly and San Jac. From there I continued along the ridge first to "Little Folly" (a small rocky out crop, insignificant as a peak but fun to climb on) and then to Folley proper. Folley is an indistinct peak by the way, and unlike SJ, the views aren't very good. From Folley, I countoured back to the saddle on the main trail near the hut and then for variety took the main trail down to the tram.
The untrailed high country of the SJ's is really great stuff. If you haven't been to Marion Mtn and Jean Peak, I think that's one of the nicest off trail hikes in Southern California.
