If you need a dry lane ball, the AMF Scamp is awesome.
I just re-named it a 'Particle Spare Ball'. It is
very clean through the heads and holds the line on
light oil. Make sure not to drill it too strong. Mine
is drilled with the pin 1 inch between my bridge and the
CG two inches below, all in line. This I have been using
on a sport shot. This is a true sleeper. Not expensive
either, payed only 69 plus shipping. Carry is also
pretty good because core is not that weak, but cover
is a very, very mild particle.
