On the games using the wire link for the flipper buttons, I always use a few tweaks to make them quick and responsive. Of course, you'll want to start with rebuilt flippers (sleeves, links, bushings, etc.). I always lube the flipper button shafts and also the pivot points and spring on the wire linkage assembly. Only a tiny dab of Teflon oil is enough. Then, I carefully reform (bend!) the wire form (be careful, because you can break it off!), so that there's just a very small amount of space between the wire and the flipper switch assembly. Also, make sure that the screws holding the switch blade assembly to the underside of the playfield are tight. You can slightly shift the position of the switch assemblies to help with the gap between them and the link wire, before tightening down the screws.
If you do all this, your flippers should be just as snappy and responsive as the type with the cabinet mounted switch assemblies. I always prefer to stick with the original design, and just try to restore all the components to as-new condition.
Things usually work as they were designed if set up properly.
