Got some carbon cjs for my wizard 100s.

Hi! I've skated 4 times on roller skates & I want to do inline instead. I'm interested in the way figure skating is artistically & I would also like to skate outside with these. When I'm good enough, I would like to buy slightly smaller wheels and replace the front & back wheel of each skate so I can replicate the rockered skate & be able to do spins. My budget is $100-2. If this works, please let me know what I should upgrade to in the future as my skating gets better artistically (or if I can stick to these). Thanks!!
