I bought mine from a forum member, didn't really look at them and chucked them in a box with some Boysen bit's I'd bought a while back.

When I came round to fit them I couldn't find all the FG spacers so I used the Boysen metal ones and fitted them along with just the carbon reeds in place of the std Honda ones (and some HRC rectifiers Andy sent me), i.e. I didn't know the pointed FG ones were Tyga as there's a million Boysen bits and bobs, I'd love to tell you how much better it goes but as I also droppped the MJ two sizes at the same time I have no concept of how much improvement was down to the reeds.

I had intended to do some back to back testing, but it (feels like??) it's going so well and hasn't missed a beat so I'm reluctant to mess about with it mid track day season.

So, to recap, just the metal spacers, HRC reed blocks and carbon reeds alone do work well.
