Ball hone puts a nice finish on the cylinders...if used properly... I still use my 2 4 in spring hones...120 and 400 grit stones.. The spring hones give a true read on the cylinder walls...where as the ball hone scratches everything.. I get the crosshatch close with the 120 grit...and finish the crosshatch with the 400 grit.. This allows the rings to seat without roughing up the new rings...and also provides excellent oil control.
