I couldn’t resist clicking the CamLam link & despite the Boyeson reputation, I doubt I’d go that route when the product listing states:
For Race Use Only - Click for Explanationwhich reveals the following:
An item sold "for race use only" does not come with a traditional manufacturer warranty. It may carry an extremely limited warranty that voids coverage the moment the part is installed or used in competitive conditions.The issue of alternatives to the reeds supplied by Gran Turismo has been aired before, notably on Scooterotica some 10 years ago & one solution mentioned is to make your own using Polini carbon fibre sheet. DIY reed manufacture is nothing new in racing circles & the way I see it, with the get-out clause stated above, easily the best solution. I dare say that alternative sheet supply to Polini would save even more costs, but I haven’t shopped around, though Polini has a good reputation.
I hope this response gives an additional view in the interest of choice
