Default Reed valve: boyesen or carbon polini?

Hello guys. What do you think is better: original boyesen reed valve or polini carbon reed valve (red colour) ?

I have not tried the Polini but I like the Pro Boyesen reeds or these from Germany seem to work well but you need to buy 2 sets to cover one reed cage.

I had carbon polini red colour but I install original reeds valve from boyesen and I think that engine works worse on boyesen reeds (plastic, no carbon) on high rpm (has no power).
