Here's a tip. We all know that SLX poles are the business, but that the clamp glue has, in the past, come loose of the pole. It doesn't help if you or your staff are a bit rough when collapsing each section - as one section slides into the other the clamps can take a bash at their base, just where the glue is.
What I've done is get a strip of duct tape 18" long (torn in half, lengthways) and wrapped it around each pole section, just below each clamp. It adds little to the collapsed length of the pole. If you let a section collapse onto the one below a bit hard the duct tape takes the impact, rather than the clamp that is above it.
So far all my clamps have stayed put since I did this.
Worth a try?
Cheers
