I'm with oldskool. If you have a typical hull, the tail will probably be sliding out when you try to turn on anything over head high. However, at 4-6+, you have a good chance of the wave being the perfect size for a hull. A nice chest high wedge? Definitely bring it with you.
If your fins aren't glassed on, you can also try bringing a set of larger fins. I feel a noticeable difference in hold on wider tailed boards when I beef up the skegs.
