Hi TJ,
I understand where you are coming from. You are more interested in having fun than having the very best competition set up. I am afraid that many of us answer these types of questions with our competitive background in our minds. From a strictly "performance" view point, then an OS .25LA, OS .20FP, Enya .30SS would probably do the best job. Of your "choices", I would go with the Fox .35, I have seen several of them fly with the Fox .35 and they flew well.
With all that said, I *would* get a stuffer back plate and one of Randy's NVA made for the Fox .35. His NVA will not leak air, is turned down to match the factory one, and will hold the setting very easily. Highly recommended.
Have Fun!!
