mad monkey or mad rat

[danny the elfman]

hey, i want a madrat for racing as a replacement from my rubbish thunder tiger (it was good up first but spares are impossible to come across) but then again people are telling me to get the madmonkey, what should i get, ive been offered a madrat for £35, and can get the madmonkey for £60, will it be worth the extra money? ive heard the midmotor design is better for grippy surfaces, but not as good as jumping, what do you think
