A Better Gear Tooth sensor

The sensors in the KOP only give you rate information and therefore make distance measuring nearly impossible. Besides, they are hard to use.

According to the 2008 Sensor Manual, the KOP gear tooth sensors give a pulse every time a tooth comes by. Where are you finding information saying they only give rate information? And what do you mean by "hard to use"? We used the ones in the 2006 kit with substantially the same software you suggest for the Honeywell parts.
