I would start off with 320-340 mains depending on your altitude, and 30 pilots.

I ran 320 mains and 30 pilots at 4500 ft, and it ran great.

Agreed, start w/ 320 mains and start w/ the stock pilots an go from there. Once you get the mains dialed in then try a 27.5 pilot and see if it helps any...adjust air screws to the pilots for throttle response...
