Need help with sizing a Fish Surfboard?

Hello everyone,

I'm wondering if anyone can give advice as to what size Fish i should get. I've been surfing for about half a year now and have two boards (9'2" HP Longboard (65.9L) and a 7'5" Malibu/Fun (40.6L)) and looking to get a Fish to add to my board arsenal and also try moving down to shorter boards. However, I do not really know how to size a fish board to get, for more info;

I'm 5'6 128lbs, surf nearly everyday (if not 4-5 days/week), my paddling is decent, I'm not too strong hence the reason looking for a fish and not a shortboard yet. I can easily catch and ride 1-3 ft waves and getting comfortable with turning and riding down the line on 4ft waves now.

Any advice can be helpful, Mahalo!
