We are pleased to say both jobs went well today. My only gripe is that the holy glider tore up our pads on both jobs. We only ruined two pads, one at each job before we decided to change to the thin glider. We also tried no glider but the challenger was too difficult to operate. Has anyone experienced this problem when using the holy glider? Mark I know this one is your #1 choice but from my experience today I am afraid to use it again. Could it be a problem with my challenger?
