I got my IQYHA 2400 mobile today finally. Looks to be all good and everything can't wait to put it under the block and try it out. I just wondered, I had it next to my 2600Mobile(R.I.P

) and I was looking at the bridges and they are all identically laser cut(as I expected) except the L6 bridges. The 2400 is cut on 1 3 and 5 and the 2600 is cut on the 1-3 or maybe just 1-2 I forget. Is this what sets the speed? Why are they cut differently?
