Talk to AUS109 - he has owned & raced every one of them & is probably the most knowledgeable person on this subject...
Holy thread resurrection batman.....
i can't remember what fin is on the EQ1.5, but I think it's an original mistral fin. Seemed ok....
the only point I'll add is that my Tiga Race, which is also a narrow tail board has a Mistral 2000 fin that is quite wide & I think about 32cm long ( it's white in colour). I find this fin would cause the tail to rail up around 17knt plus, where the Eq1.2 & EQ2 have narrower fins and don't do this.
check out Windpower in the USA for spares, they still race them and are extremely helpful. They for instance 100% recommended the knuckle universal for the board. Make sure you push the locking lever all the way down or the uni can pop out. The "flat " setting is for surf.
enjoy, they are fun boards
