Depends on what you define properly as
Did it spin the tires,yes
did it do the job it was meant to do, yes
Was it overly impressive over my setup, no
I will say that you can not just throw in a heavy secondary and be set. The primary and secondary will need to compliment each other. For the normal rider who only mud rides you will not feel a difference by going full kit with weights instead of a primary/secondary that compliment each other.
For someone who likes to tinker and get the most out there bikes for fast paced riding or race applications then yes the Dalton kit is great. There weights are a far better profile than epi. I will probably end up with some in my bike but not because of the advantage will running big tires but for what they can do for me on the track.
If you'll suggest a proper setup for a Dalton kit then ill try it out but the normal mud rider really has no need for the whole kit.
The epi kits for big tires are complete jokes. This is not the same case for the Dalton as it does its job but IMO its not worth it to the average Joe.
