I am just thinking out aloud (on the internet, that's unusual!) that my ideal quiver would be something like:
1. 5'8" Potatonator (33.9L)
2. 6'0" Spitfire (35.3L)
3. 6'2" Hellfire (33.7L)
4. 6'4" MB (34.6L) / 6'6" MB (34.5) / 6'5" HR (33.5L) / 6'5" Lost F1 (33.9L) / 6'8" Flexfire pin (33.9L) /
The #4 may not even be necessary. The hellfire may well prove to have the ability to surf waves as big as I want to. It's always hard to say, I've seen 6' in some places I'm afraid of and 10' in others where I have no reluctance (been a while though but usually the problem is that kind of wave will be crowded heavily).
I know there is quite a bit of overlap between #1, 2 and 3 but I like the idea of a fair bit of overlap so that if things change quickly or you choose the wrong board for the conditions what you have should still work. I used to bring 2 boards but with warmer weather at the moment and the warnings about not baking my boards in the car I don't during summer.
I've never tried a spitfire but after riding my hellfire I really like the extra bite in the tail and I think a spit would give that to me over the dom that I currently have which is great in average full surf but I think the spit would be even better.
What's your ideal quiver?
