The smaller gates are better for higher boost. If you ever want 19-30psi you will probably want a smaller gate.

for 10-12psi I would buy a 10psi spring and use a boost controller to get 10-15~ easily, total boost pressure.

So like a 50mm with a 10psi spring would be a good start?

Sure. My JGS 500R nets about 8psi on the heavy spring in a very mild 6.0.
