While not as marketable, I think SF really should have gone back a re-profiled their other wooden coasters. Screamin' Eagle and Boss look like great rides, but their reputations seem mediocre at best. Some TLC for these coasters could benefit the park more than a new coaster.
On the other hand, A great new coaster will generate traffic, and SF couldn't have gone with a better coaster company to provide a ride all together different from what they already have. Since this will be the park's twister wooden coaster, GCI is really the perfect choice. Hopefully, the other woodies will receive tune-ups in the future.
