this triangle is great. for really tight racks and very easy to use. there is plenty of room for the rack and unlike standard triangles, will not cling to the balls when released, leaving them perfectly still. it has made a world of difference to the players, as it results in a really good break, every time. the rollers under the triangle are a great feature, as it stops friction on the baise when moving the rack within the triangle, and will roll into place over the spot very well for great placement.
