Evo 74 2006 spinning out

[chiel]

A coupe of months ago I bought a Evo 74 2006, which I a used quite a lot since then. After a couple of days adjusting my style to this type of board I am extremely pleased with the board. (using 5.2, 4.7 and 4.2 NP Combats)

But while pointing or doing (sort of) high speed bottom turns the board/fin tends to spin out abruptly. Is that just me or maybe the trim? Or does it have to do with the fin (22 Drake) which seems to have a lot of flex?

Regards,

Chiel
