This question requires a bit of an elaborating answer. EVOs are in a way very tolerant to fin size - you can go big or you can go small depending on what factors of the ride you want to change. Scott McK replied in another thread that he pretty much never uses bigger than Natural 23 on his E80, even with 5.7. This is fine if you are a very good sailor and either ride fast and powered up or maybe are riding very nice waves (possibly schlogging to get out). Personally I tend to use anything from 22-25 Drake Natural on the E80 with sails around 5.7. When conditions are such that I want the float the E80 provides but still will have pretty good speed when riding the wave, I tend to go for smaller to loosen up the board in the top turn. If wave riding speeds are slower and I'm maybe underpowered and/or if I want some more directional feel for jumping I may go bigger.
When you go for a small fin it takes more technique to get planing early and go upwind and vive versa. So I would say its a trade off between immaculate wave riding and "straight line practicality".
Two things make it complicated to reach the perfect compromise by pure trial and error. First, without lots of experience, its hard to pinpoint when one has a to big fin in the wave riding. Second, there are a few little tricks for planing early with an EVO. With a small fin one has to learn them to be effective. With a bigger fin one can get by pretty much without using these tricks, but in the end one will still not be as effective as one could be. Both these issues implies its good to try a comparatively small fin now and then and then go out with a positive attitude and really try to use that smaller fin instead of blaming it for the lack of "positive feedback" in a straightline.
Puh, all that said, most people tend to end up liking the Drake 25 for 5.7. The 26 could work too, but in my opinion its overkill. Even with a super big fin, the EVO will never get the kind of feel that the more freeride oriented JP FSW provides.
