My thought on the glider purpose was a hybrid approach: insert like a flange tip, but a little more comfortable like a foam tip. One shouldn't have to compress as the namesake of the tip should "glide" right in. I use to swear by them, but after too many "off" presentations, I discovered the glider tips were tilting in my canal over time and needed adjustments, which altered the sound some what, but noticeable. I'm with you, foam tips all the way. The angle position with those are consistent. I don't use any silicone tips with my Etys as they create a suction like pressure that hurts a little when removing them.
It's all about deep insertions with the ER4 line. Mine goes so far in, facing me, you can only see the braided cable hanging down against my ear lobes. It makes my wife cringe and I love it.
