Looking at trying a Fury 4 to help get a heavy load up. (BFL co’s like to travel heavy). Currently turning a 26P Tempest Plus @ 5800rpm. I’m not sure if I am going to need a 25 or 24 Fury 4. I don’t have access to try one before I $$ for a new one. Any suggestions/opinions appreciated. (2014 Pro XS 250/2014 Z9/ two 8’ PP)
