Hi there, the Blast is more of a straight line free ride board, which is also very good at tighter gybes/manouevers - but if you are struggling with the FW105, then try a smaller size like 95L - the width difference to the 105 should make a good difference, almost similar width to the Blast 100 - but I think sounds better to learn/improve your gybing? Of course if you want to go faster, then the Blast 100 is also a great option too.
