need to swap shortboard for something slightly bigger!!

[T4duude]

I have a brand new (been in the water 3 times) nigel semmons shortboard with fcs fins, pad and bag, 6.0' x 18 1/2'' x 2 3/16'' which i need to swap with something slightly bigger in the same condition as i dont surf very often and will take me forever to get used to it. I'm looking for something like a 6.4' x 19 1/2''x 2 1/2''

Anyone got anything they might want to swap?
