I'm using EBC red pads for the front and I have the opposite problem.
They don't grab hard enough, which might be the right pad for you?
They work pretty good in dry conditions, but really fade in the wet.
They were also thicker than original, it took a while for them to bed in enough so they wouldn't make contact with the rotor while not engaged.
I'm going to try the R series pads #FA131R for the rear and see how they work out.
For the ultimate durability EBC presents it's "R" series high density series pads. A sintered copper material made in our own USA facility, the "R" series of heavy duty ATV and moto-x pads have become an aftermarket standard offering high durability, high resistance to contamination by mud, water, sand and grit etc. offering reduced disc damage and long pad life. Sintered brakes are a very modern and interesting technology, click here to read more about EBC
Here's a brake selector chart from EBC

It would be great if Roscoe or other vet riders would chime in on the right pads front and rear.
