I've tried swisstop and koolstop and although they did stop they wore out too fast

Tried BBBs next and they naturally didn't stop quite as well but were half the cost. The last time I was in my lbs was selling
xlc tripple compound inserts for half the price again, didn't expect the best but I was strapped for cash and thought I try them out. I was pleasantly surprised maybe not quite as good as swis/koolstop but they are better than BBB. If the lbs back home (400miles away) still sells them when I'm back for a visit, I'll buy some for spares
