I HAVE THE MAREK 141 WITH THE 1.1 P-WINGS AND ITS A BIT LOOSE. I WANTED TO KNOW, SINCE THE MAREK WAS BASED OFF THE SAME SHAPE, IF THE CLASH 142 WAS A BIT TIGHTER.
the clash comes with even smaller fins so it definitely wont be tighter stock. why dont you just try some bigger fins on the marek? that should help the looseness.
