Yes Sendai45, I can see where you are coming from now but if you use a bit of rope, cloth or elestic it can make a big difference to the result. I used rope and cloth in my first solution, due to force of habbit, then I suddenly realised that bars and steel plate worked out much cheaper.
I have no rope, cloth or elastic in my final solution so it looks like I am still missing something The result in the B League has compensated for this one
