The Blue Vibe is a great ball, but can definitely be used for medium as well as light, depending on how you drill it. I have mine drilled like this:
0 0 P
CG x-hole
0
I just had the x-hole drilled last night because I wanted to tame it down. Now it should fit in between my U-Turn Reactive and Tropical Storm. Great ball and great hit.
