Just saw that Bowlingball.com has T-Road Solids and Rapid Fire Solids for $72, T-Road Pearls and Rapid Fire Pearls for $84, and Gravity Shifts and Attitude Shifts for $98.
I love my T-Road Pearl so much I'm tempted to buy another. I've often considered a 3-ball arsenal of a T-Road Solid and 2 Pearls -- one with a weak drilling for dry lanes. Too bad I have a new baby and no $ for equipment!
