Hi I have just recently went to a local surf shop and was told to get a 5' 10",5 fin combo, round nose fish (This board is based off of the Lost RNF). I am 5'3" and 130lbs. I usually surf anywhere from head to overhead high surf. I have been using a 6'4" short board and it wasn't responsive at all. I am an intermediate surfer who is looking for a more responsive board. Is this the board for me?

Thank you for your help!
