It's a good plan, springs help the likes of DTK, Ripper and of course Titan be the lowest robots out there. They don't work too well for flippers, mind you, and they don't half chew up the floor!
Oh, and Gareth, Titan and Dystopia may have had similar ground clearances when they last properly fought, back at Gloucester 2012 when it was still Ripper, but since then she's had springs added, and recently 2kg of lead in the tips. No flipper can put as much pressure on the ground as that.
Bearing that in mind, is the extra hassle of springs worth it, knowing you can't win the ground clearance battle?
