michell tt owners, any experience w/ pedersen mods

I have been reading about the gert pedersen armboard mods and plinth mods and was wondering if anyone has tried them or has first hand experience with them??
I did the Pedersen mods about two years ago. They were not easy to do, but I really liked the modified deck. I actually noticed more difference with the "chassis" mods than the armboard....but there are so many factors. All I can say is he is a great guy, very helpful and pretty accurate in the way he describes the benefit of the mods.
Best of luck,
