anyone heard of these, (might be called precise brand) How do they compare to the other brands?

 

I've got the 3.73's in my 10bolt. They are holding up well to the high 1.7 60ft's I'm throwing at it so they are pretty decent in my book. On a side note...IMO the brand of gears isn't near as important as the person that sets them up

 

Precision Gear is one of the better brands.
