Fish-Dimitrov-Isner-Kohlschreiber parlay for tomorrow, good or bad idea?

[PMcG012]

Is there any reason one or more of the above should not win? From my limited tennis knowledge they all seem to be playing well, and Kohlschreiber will probably have extra motivation playing in Germany. I even considered
throwing Sock in there too, but that seems more risky. Thoughts?

Dont touch Sock IMO. Of the 4, Fish would worry me the most.
