The problem with string pinsetters is that pins can be knocked over without being touched. We've all seen the airborne pin that flies over another pin. With string pinsetters, that flying pin will most likely yank on the string and take out the standing pin.

There's an alley here in Sacramento where the last 12 lanes of the house have these. As they never will be sanctioned for league or tournaments, the only things they are used for are parties and open/glow bowling. Besides, if any serious bowler gets those as a pair and wants them, they really aren't bowling on them to score or anything; they are there to see how their ball is reacting to the oil and continuation through the pin deck.

Now, keep in mind that QubicaAMF offers those types of pinsetters:

That is what this particular house in Sacramento uses, although the first 32 lanes there were updated to use the XLI Edge pinsetters over the old mid-1970s garbage they were using.
