Hey he is using it Cause that is the latest and so far gave him an Edge for Mod racing cause the Belt absorbs the initial torque thus giving a smoother take off. compared to the torque stir that a shaft has. but Mind you he is not thinking of Damages and Expenses... we are...
Let me give you some of the Parts that gets damaged with that I have come across with Cyclone and Pro4.

Bevel gears
One Way - Very Rare

Oneway - I have seen 4 Cyclone users who replaced thiers from the time since Cyclone came out
Servo saver - Very Rare, but Due to that it is single compared to the Pair that Pro4 has it absorbs the Steering impact from time to time.
Shock Tower Holder - Commonly Bent

Both Problems can be Easily Solved.. though you might want to consider how much you will spend to Fix the problems on either Kit.
but then again, If you Are Hara.... you will not have to think of the Expenses
if you are a just a Hobbyist like me, then I might want to consisder the less expensive Kit to maintain.
Mind you,the price of Bevel gears are 9X less than that of a Oneway for a Cyclone. Belts don't come Cheap too.

the rest is up to you all to Decide... but just keep this up in your Head.

He who Braggs a lot about the Flaws of others have more Flaws in Him... somewhere.

have a great Racing! Belt or Shaft... it doesnt Matter a lot...
Its your attitude towards others that will matter in the R/C community
as you say cyclone the middle one way i have seem few people change it becasue the housing was break
fir the shock tower holder? they have been replace it with the new design more strengthen part some more now they using 3.5mm shock tower so i nearly impossible to bent the shock tower holder.
another thing is cyclone upper deck i have break 2 deck just accidently hit someone car only.
about pro 4 diff bevel gear for one way and spool there will be stripe when you get hard impact but it will be solve by how you shim you one way and spool. i have used it for 5 month without changing the diff gear the only thing i need always changing is the small bevel gear that connect the shaft due to the e-clips design so i have change it to 2005 spec aluminium bevel gear and shaft.
