I have a cupped S215 prop that I run on either my modded BJ29 or my Sprint Cat. Both are 6s boats. The only difference is the BJ29 has a 1400 kv Leopard 3674 motor while the Sprint Cat has a 1600 kv Leopard 4082. Both are running SK180 v2 controllers so I have plenty of headroom.

Just looking to play around with a different prop and improve on the S215 which has an overall pitch of 2.5" (1.6"x40.6 mm).

The X445 has nearly the same pitch of 2.47" (1.4"x45 mm).

I have yet to buy the X or M 445, and would like to know if anyone thinks the Octura 445 prop would be an improvement over the S215.

btw, I run the smaller prop on the Sprint Cat in an effort to slow it down a bit for smaller ponds. Its an absolute mad man otherwise.
