I'll agree that driving with a one-way is harder for a beginners, but I have a solution for those beginners, DON'T RUN ONE. Besides, how many beginners are going to compete at the national level? Just because some people find them hard to drive with does'nt mean you should slow down the others who can drive with one. Plus it is my opinion that some cars work better with a diff than other cars. Like the tc3 for example. The yoke sp, however, was designed with the one-ways. As for cleaner driving I would disagree. In the weeks leading up to the Reedy Race many of the pro mod drivers who use one-ways started running with diffs at SoCal. I remember the first time they ran being one of the worst pro mod races I had seen for a long time.
