Board Size Member Advice

Just a quick one. Take the advice of store owners and this site. I'm 47 yo, average ability, 6'0" tall and 91 kg. Bought the 6'6" dom - fun but way to big. Feel like I'm on a mini mal where-as my 6'6" hellfire feels great (but I think could smaller on that as well). Its hard to get your head around after surfing nothing shorter than 7'2" PU's at margs for nearly 20 years. The beauty of Firewire is you can go shorter at a time in life when you thought you would be going longer. Love the sticks! Just my two bobs worth!
