Think about this for a second, can you write any faster with a pen and paper writing word versus writing words. No I didn't make a mistake, read that again. What I am saying is that how could you possibly write 100 words slower on a MM than you could write 100 words slower linearly, if you are writing at I dont' know 50 words per minute.
I personally have gone straight MM on all my classes at College, and I will NEVER go back. I would be completely ludicris to go back after you have experience the benefit of Mind Maps. Visually they help me tremendously, without much study of the MMs I can pick a class then review the MMs in my head, not 100%, but I can picture what I have written down, kind of a hard chore with regular note taking.
Try and go straight Mind Maps for all your classes, I would doubt you would want to go back.
