I don't see a lot of benefit. In the WPC case, shrinking let me eliminate some cables. Stern playfield cables already connect directly to the board. The only way to eliminate more cables would be to piggyback it directly on a power driver connector, and I don't want to do that. The SMD microcontroller is slightly less work on my end, but not worth a board rev.
The USB connector might push me over the edge, though. The board assembly house never gets the through hole case pins on the old one soldered good enough, and I end up having to retouch all of them. The USB connector change doesn't force a board shrink, and the new Mini PCB is a 4-layer PCB, making it more expensive. On WPC, that cost is more than offset by the simplified cables, but on Stern where the cables would remain the same, it wouldn't be. It's a lot of things to consider.
Quoted from Whysnow:I would liek to know if/how wlel this works with the comet 2SMD frosteds I use in all my games.
Any input from you or anyone that has done so would be greatly appreciated.
I've used these in a few inserts in Stern games, and they worked just as well as my goto 1SMD frosted. I don't remember using them in any WPC games, but I wouldn't expect any difference in the performance.
