That rps isn't too hard to get, even a motor change will do that alone. So you don't have to go crazy. However a 13:1 gearset with a 22tpa (20k) motor on a 3 cell lipo will yield a really good rps with really good trigger response without too much overspin. That would be about 25rps.
But that 30k motor on a 3 cell lipo with stock gears would also hit about 25rps, it just may have more overspin with the indoor spring, but with that mosfet that's manageable.
As for barrels, the lambda 6.01 is a great barrel, but avoid their cheap coated steel ones, they are trash, go for the nicer stainless steel or go with a pdi 6.01
6.01 barrels are good, but not forgiving. It must be straight, good bbs must be used, and it must be cleaned often. Even then accuracy gains aren't guaranteed. But a fps boost is typically achieved due to the efficiency.
A 6.03 or 6.05 is more forgiving, and more accurate honestly, a laylax 6.03 barrel isn't a bad choice ever. I have a lapped one, and it is the best i have even after 6 years.
