Help decided 1/10 off road for brushless

[wongy008]

After years of going nitro, the brushless scene is interesting me and i want to build a brushless tamiya 1/10 Rc buggie

only thing is i dont know which model to use. which is best suited to running brushless without me forever renewing bits

i origionally wanted to run a brushless top force as ive always wanted one

i then found myself being directed to dark impact, durga, ive looked into the DI and durga

only thing that concernes me it the durge is belt driven, when i use to run a kyosho pure 10 spider 2 the belts would not hold up and the diff plastics wear away quickly

to me the shaft seems a more reliable option

what are your opinions

will the DI withstand abuse from mamba 5700
i liked both but then saw a review of the zx5 and it seems like a interesting car. it looks like a pretty purposefull car

im not gonna run the car comp or club use. its purely just for running for fun in a park or something
