I've had mixed experiences with Slazenger pads. Had a pair from about 1998 - V600 Ultimates I think - they werre awesome and I got several seasons use out of them... So when they eventually gave up the ghost, I didn't hesitate in buying another pair in an updated model... which fell apart after less than 2 seasons So not had another pair since.
i had a pair of the Salzenger master class last year. only lasted half a season. The bowling machine hit them at 85mph and split the stitching on the front shin. took them back to owzat cricket who refunded my cash. Ended up with some salix pod pro and they are superb. Very comfortable.
