3 come to mind. The inland surfer blue lake is a good board for that weight. Also the composite x 5.0 from The Walker Project. A smed wombat would be good, but at 5ft, not 4'6".
You should check out the 5'0" surf style from Triple X surf and skim or their 54 or 58 composite skims. I have a couple buddies that ride with me and they like the 54 and 58 skims
