I this I think you should add Eged Redstone. It will look like the a rail but the middle is redstone dust. Ever been tired of different contraptions keep mixing together with that ordinary redstone dust accidently connecting with other things? This is why you should add edged redstone. Edged redstone will not connect with other redstone lines except the one it's on. Please add this because if not, Redstone will be very annoying. ( I picked my device but it's ment to be all. )
