Played some solid w-ball on Sundy, in honor of our fallen soldiers.
We played this version under which, instead of keeping track of imaginary baserunners, you have to actually run on a hit and then get an increasing number of points for each base you get to safely; fielders throw the runner out by getting the ball back to the mound with the runner off-base.
It makes playing with more than two people easier because each person has their own score, and you don't have to worry about teams or anything. And the get-the-ball-to-the-mound dynamic introduces some of the interesting parts of baseball that are left out from the wiffle rules I've played under before: for example, if the pitcher runs to field a grounder, one of the other players on defense needs to cover the mound to get the out; and it actually becomes advantageous to throw pitches that will be hit for grounders that will be fielded for an out, whereas under the official rules it's often better to go for a fly out.
We also played using the softball ("king") size wiffle ball, which was not as weird as I had anticipated. It actually seemed to curve better than the baseball size, though maybe it was just that the larger size made the motion more visible. It's definitely easier to jam a finger in one of the holes (nullus) to throw a changeup, though. In any case, I had some success with the changeup/changeup combo, and with throwing a curve for a groundout, though my slider was as hittable as ever.
