Well, Transitions are deceiving. I thought I would have a lot more hair to play with after my 1 year transition, but I didn't. I never took shrinkage into account, well I did, but I didn't think it would be as much as it actually turned out to be since I am a 3c head.
If you want a lot of hair to play with after the BC, a long term transition would be the logical route, maybe 2-3 years.
