[QUOTE="AlluvialRic, post: 22531, member: 459"] G'day Wal I'd have to disagree a bit with this. The Hex/round Holes in the mats I have always used (common front door mats) are 30mm dia and the Diamond matting each diamond is 30mm x 50mm which is as big as the expanded mesh I sometimes use. I have never had a problem with them clogging up. Most highbankers I have used and come across over the last 30 years classify to about 1/4" (6mm) whether they use punch plate, flat expanded mesh or cable tray. I can't comment on those using parallel bars as I've never used them. I've been going to Tuena for many years and have never had any problems with matting or riffles clogging. I do also use Expanded mesh down there and also hungarian style riffles and have experimented with a few types of matting under them. At Oallen the place is full of ironstone and that is one of the indicators I look for. Cheers Ric [/QUOTE]
