i think the open class is a great addition to the sport. like everybody has stated, the ability to stand/kneel has made a return. this makes the engineer of this class a first class doctor able to cure all ills.
the people who entered it are genuine in there disabilty. it wil continue in my opinion and prosper the sport as a whole. as all new things it will take time to grow. credit to the people who took part, shame on you, all those in the past who have used a different set of rules for advantage for some personal glory.
