Yeah Jason, Steph, and Kyle went over Sharkfin Col on that trip which requires a rap. The more "standard" approach involves traversing the east face of Boston Peak, which is easy climbing but is exposed.
The south side would be less technical but you could avoid Sharkfin Col or the Boston traverse by dropping into Horseshoe Basin off of Sahale Arm and climbing up from there.
We skied the south face one summer when the N Face wasn't in. I'd say its pretty comparable to W Ridge of Eldo as far as steepness, etc.
