This is a LD shaft. If you're looking for an LD shaft but don't want to pay $300 for something ... this is a pretty good deal. Sub $200 shaft, good wood, good hit, good ferrule, and worth the price if you're hunting LD stuff. The one I'm basing my review on has a 5/16x14 thread .. and I tried it on 2 Joss cues and a Schon. It has a middle cue hit feel to it, and no vibration in your bridge hand. Well worth the money.
