I've had MA-V1's on my R33 - good for a budget tyre. Grip was quite good actually, and very progressive. You always knew just before they were about to let go, giving you time to correct. Khumo's are supposed to be quite good, as the Proxes 4's. My dad has proxes 4's on his BA XR6T and he's pretty happy with them, then again, he's not exactly a lead foot any more (though he does have 272rwkw LOL).
Perhaps get a price on the Maxxis MA-Z1's - they would be more comparable to the other 2 you have there I think, performance wise, and they placed 3rd in the Motor Tyre Test in 07 (or was it 06?) amongst tyres more than twice their price!
