I think you both are right if you practice 1a for 7 months your learn so many elements tricks. But with 2a unless you get Inside loops you can progress maybe around the world but the progress compared with 1a is different.
You should not focus on 2a at least this is what I did most of the time I do 1a but at night half hour I do 2a that to just messing around and I thought that I could never do loops but because in the whole day i did 1a it gave me enough mind to keep doing forward passes 1 loops 2 loops and one day it just came I did 9. Then I progressed fast warp dripe hop the fence regens.
