Hi Brian, i too have been a long time user of Sensor, never had a problem with the spools in the past. When the "NEW " Hyper Sensor came out, i switched to that, and again, never had a problem with the spools. Maybe, the original Sensor you've been buying is very very old stock, and that's why the spools have perished and become brittle and fragile.
