The Magma is a well-gliding, stable-to-overstable mid-range disc. It does not turn over even with higher speeds, but flies straight until it slows down for a predictable fade. Even for lower arm speeds the Magma will not be too overstable, but remains a very easy to control and reliable disc.
Magma is made of H9 plastic material, which is very durable yet flexible, and with a good grip compared to other premium plastics. H9 is also one of the best materials for dyeing.
