There are no yellow L34 callaway balls.The Yellow callaway balls with the same attributes except meter speed of the L34 Callaway is the L39 Callaway.
A bit depressing, but unless they add the yellow option to the L34 Calaway or the Max Pro ball, I just won't use them. I just can't tame the meter speed of the options for yellow callaways. Either it's the poor vision in one eye or too many surgeries in my mouse hand, I really don't know (both due to military service). Too bad, I really want to use them. The L35 specs of the ball is perfect for my way of planning shots. Plus it's the ball I'm gaming IRL and love the triple track.
I'll just stick with the Titleists for now, which will probably make WGT happy. ;-)
