How you're using the boat will play the biggest role in which prop makes the most sense for you, and what works well for one person could be terrible for someone else.
If you're just looking for the best acceleration and low speed performance, with no concern for top end, then upgrading
ACME's 1285 will give you the best possible performance.
If you want a recommendation based on your individual application (altitude, ballast, usage) just contact us.
