I have a RICO'd SD-73 CLASSIC, and it is real smooth. Nice big arc hard hitting ball for squirrely lanes. My brother shot 800 a couple of weeks ago with it. Also have a stacked leverage and a pin above the middle finger versions. The RICO and stacked hook about the same number of boards with the RICO being a little earlier. The stacked slide a little more with a hard arc to pocket while the pin out skid snaps. Horizon has a modified version on this block is probalbly smoother over all. Should give you a nice arcing predictable reaction.
