Hi J,
Sorry, not that easy. You're asking a football player what kind of cleats he uses from a very muddy field to dry ground(astro turf being dry lanes), what do you think the football player would answer? A one inch cleat for mud will stick or create too much friction and/or traction on dry ground. A heavy oil ball will create too much friction on a med condition. The half inch cleat will slip in mud as a med ball will slide in heavy oil. I could eliminate almost half the balls in my shop if they made a ball that covered this range.
I'd still have to recommend 2 balls for you. Based on the numbers, the Animal sounds like a great ball for heavy oil and for the med conditions, I feel a Freak Out would fit in nicely for a tweener. Hope this info helps and feel free to contact me if you have any further questions, thanks.
