I have some of his replica lightening weights he sent me to try out. IIRC they are the same as his adjustable ones, just, well, not adjustable without the drill method. I have 2 sets one for low alt riding and one for higher stuff and I can just swap primary springs to make quick fine tune adjustments for localities if I want.
They work way better then the 10 series. Way more tip weight so they drive a lot harder into the shift curve. That being said I am running mine with the full clutch setup front and back supplied by indy. (per TRS spec) This setup is a NICE improvement over the stock clutching which IMO runs well but makes WAY too much heat and doesn't shift out nearly as well when you have the space to let the sled shift out.
