The SLAIDi from Prodiscus was PDGA Approved on 9-12-2012.
"SLAIDi is the latest release from Prodiscus. It's more stable and a bit slower than the longest driver of Prodiscus line-up, LEGENDa. SLAIDi glides nicely and with a powerfull drive you can really make the long s-curves. The Premium plastic is the stable one for all winds. It's durable and grippy in all weather. The Basic plastic offers even more grip and it fits nicely for beginners as it's the more understable plastic of the two." - Prodiscus
