Why would you want to speed glue long pips? I have heard of players doing funny things like putting glue on only part of the rubber so there are spots that are extra dead and others that adhere to the blade and that makes it harder to tell what spin is coming off the racket because it will respond differently where the rubber is glued better than it will where the rubber is not glued properly. However, the expansion of the sponge that goes with speed gluing causes the there to be more tension in the TOPSHEET of a SMOOTH RUBBER and therefore there is more dwell time, the ball sinks in more, the topsheet grabs the ball more and you get more spin, speed, and control.
With pips, the tension of the rubber should not change the pips themselves in any specific way. All it would do is make it as though the pips were on a thicker sponge. I don't really know. But I think a thin sponge would be for control and using thicker sponge might not be what you want with long pips.
Perhaps someone who uses long pimpled rubber would be able to give a better answer though.
