I don't have the original hy-road, but I have the pearl and nano. The balls still hit hard at 14lbs. In fact, I do not agree with the loss of hitting power at 14. Since switching nearly two years ago, I do not leave more corners pins than while throwing 15. I also seem to carry more light mixers. My averages have gone up as well. All things being equal, maybe 14 carries less. But let's face it, they usually aren't equal when dropping weight. I have a far easier time manipulating my release than I did at 15.
As for the Shock, I have one waiting to be drilled up. Finally getting one in 14 after owning two at 15. One of the best balls I've ever had. I just got my VSP about a week ago. I can see using the combo on a lot of conditions, particularly the house shot.
