Hard pressed Triangle for me. They require no maintenance. Old school tips. There is so much hype and marketing in pool to separate you from your dollars. Triangles are about a buck apiece. If you want to spend $20 on a tip, have a ball. You can by an $1800 production cue too. Or $500 on a production shaft.
I have heard that if you take a box of Triangle tips and drop them in a container of water, the hard ones will sink. Don't know if this is a wive's tale or not.
I have four hard maple shafts, all with Triangles. All four shafts are pretty much identical. Two of the shafts have a distinct sound and feedback different than the other two.
