Honestly wouldn't matter to me as long as it's a great game. Unfortunately id say about 90% of the pins on location are in such bad shape after I've played a ball or 2 and realize the flippers aren't even strong enough to make a steep ramp shot I walk away.
Most pins on locations these days are Sterns since quite a few op's have started to sell off the old B/W's titles that they can make money on. I've never thought abkut buying a routed Stern for obvious reasons.
