I turned hansel when I was your size (not much bigger now), an it's earnt me loads since! I just converted to hansel at lc, then followed val's guide (still on it, just bought by 11bill land)
I make 22 with 6 SoS. Ive grown as a spy, and as an attack then converted. Attack first, then converted was the faster way for me. I made more in bonus as a hansel, but i grew faster due to not having to buy pots for hitting as an attack build. There wasnt much difference between amounts of bonus i received. My spy was about the same as yours is now.
I agree with miss_b, if you're new I'd start as attack and convert. It's all up to personal opinion, just try what you think, and tweak it if you don't like it.
