Aftermarket reed cage / block assembly

Where petals are allowed but the cage is not, a full reed-block kit is illegal.

This is one body's answer, not the sport's. You are bound by whichever body sanctions the event you enter, and where both govern you, you are held to the stricter of the two. The differences are set out in the rulebook comparison.

Ski Lites is the trap: petals yes, cage no. Split these into separate SKUs.
