With the Old Seraphim (that ran at Swindon) I had all the flippers try to do something but most could hardly get that height the ones that did reach the underside of the Seraphim just about knocked it up on one wheel for about 1 second then Seraphim just drove over it!!!
The pushers are all too low and Seraphim drove over them too. The only robot that would have any effect on Seraphim other than spinners would be Little Hitter. But I am happy to exchange blows with that one anyday.
