The Pro12 derby! I think the Kings and their stars Cloete and Cronje will sign off with a seventh victory in what has been a great season for them given the incredibly low expectations at the start. I'm impressed by their coaching, and their temprement in close matches.
The Cheetahs have been all over the place all year. They can look like world beaters or abject in the space of 5 mins. Incredibly inconsistent. It'd do my head in to support them.
