Ive driven both, the ASD's dock no different than my #6 set up...there is alot of wrong information out there. They also get up on plane just as good once set up properly with the correct props and can handle more hp and torqe than the NXT set up. Less parts easier to fix just not nearly as many repair shops as the big Monopoly co. These drive are used mainly over seas.. where we are brain washed that Merc. is the only co. to buy. I'm glad Ilmor and a few other co.s came on board.
