Re: Is a HighFive a good idea?
The High Five would be a great fit for your needs. FWIW Quicksilver (the cheaper Merc props) now has the high five but they call it the QST5, going price for a new HighFive is 470, for a QST5 is 380. There are at least 3 versions of the merc HighFive, the part number for the new one is 48-815758-A46 (19"). With the A46 the version number.
A46 Flo-Torq II hub system and PVS-equipped (plactic vent holes)
A45 Flo-Torq II hub system and PVS for 23" and up
A44... ??
The PVS system is sorta cool plastic vent plugs that come in 4 sizes, no- hole, small, med and large vent holes. The vents can help with hole-shot.
