Replying to Do I need a narrower ski?

Yo everyone, I'm a fairly advanced skier. I mostly ski off piste but next season I want to focus more on learning and mastering basic tricks (360s, butters, rails etc...)

I currently have a pair of Prodigy 3.0 mounted -3.5cm from tc and I have a nice deal on a pair of Prodigy 1.0 that I could use as a "dedicated" jib ski.

How much of a difference would having a narrower ski make in learning new tricks? Would it be that much of a difference?
Or am I a pussy and should just use my 3.0?
