The LP Triangle is a basic triangle that will get the job done.  I don't know all that much about triangles, but I do know that this one will sound great for recording sessions.  I admit that I have only used this a few times as I don't often have a need for it, but when I do use it I'm happy with the results.  The instrument is easy to play as long as you know how to hit it right and is overall pretty sturdy and built well.  I haven't used it for anything other than recording and I've taken a few different approaches to recording this instrument, all of which I believe are pretty valid.  What I would usually do is place a Shure SM 57 about six inches away from the instrument and will give you a pretty accurate sound.  I have also recorded the LP Triangle with a condenser microphone (a Neumann U 87) but I find that even though this will pick up more of the subtleties, it isn't always necessary and I would only use one if the part needs more detail.  I haven't used too many other triangles out there, but I'm confident that this one is just about as good as any of them out there.  It has a crisp tone quality and should last a lifetime as long as you don't lose it as I can't see too many ways that you could break this guy.  The price of the LP Triangle is the best part as you are getting a quality instrument for a very reasonable price.  If you are looking for a triangle to add to your percussion collection, I would look no further than the LP Triangle as it will give you a good quality instrument for an even better price.
