Stainless props perform better than ally and cut through the water better. So you can go up one pitch.
That was the advice I got from Oakley Marine when I discussed props with them a couple of years ago, he said because the SS blades are stiffer and thus usually thinner on a stainless prop you can increase the pitch by an inch with no problems.
I didn't in the end, because I figured the risk of rotavating a rocky beach meant it was better to stick with a cheaper alli one so I just bent the prop not something more expensive.
