Twist and Pulse now actually do train, teach and help up and coming dancers, so they are doing exactly what they say they are doing.
They didn't just rush a group together so that they could get back on TV.
Also, just because someone isn't on TV, does not mean that they are not highly talented and not working - Go watch a Westend show and you will see 1000s of non-TV people who are so talented they would blow every act that has ever been on BGT out the water.
