Replying to I need help in the park

hey, Im new to the park, I only started last year doing straight airs, and this year I want to get better at the park...So whats the easyest trick to start with? I can allready do 180's on my backyard jump, but thats all...
I learned easy straight rails this year too, so whats the easyest rail to learn next?
And finaly, Im 5'2 and I have 137cm jr 1080's I got last year but I had a huge growth spert this summer, so Im like 3' taller, so would getting something bigger be easyer to learn stuff in the park?
any help would be good
thanks
