I use the golf clicker too, but have settled on 20 minutes a side. I keep two cartridges, an SPU Synergy and Benz Micro LP and have re tipped them both once.There seems to be two issues regarding cartridge life, sound quality and record wear. Of the two, record wear concerns me most, my ears are too old to notice sound degradation anyway.
Anyone care to comment, assuming no damage, which would tend to come first, sound decline or record damage? I have always assumed it's sound degradation.
