5.5 Uni...sounds like the board stoppers are similar to the F18's.
Will probably give the roller skate toe stops a shot this season to see how they work out.
Thanks, Tom G
Oh, you've got those big rubber door stop bumpers (those are completely different than the "Inter" series board stops). I recall having issues with those on my 6.0 ... but I did the same solution...tied a line through the hole.
