Just a point to note, the last time I ordered plastic tops, I had to drill them out a little in order to get the metal spike through as the holes were far too tight. The first two I forced through and it split the tops. Having then drilled them out it weakened them considerably and it made them difficult to extract without them braking, hence why I was looking at Trazan Pegs. the more I think of it, the more I think I will give them a go. I think a peg puller shaped more like a claw would work very well with them, but I cant think I have ever seen one.
