I've been in and out of this thread off and on since it started and in all of the excellent shooting form and style advice from Nate and others. 3-under seems to be shunned for those shooting these bows. I recall Rob referring to 3-under as a "rickety affair", perhaps due to the noise, but that's all that I recall.
I shot split all my life until 2 years ago and started shooting my recurves 3-under with greater accuracy and consistency. Yes, it is noiser, and I don't like that, but I enjoy the consistency.
It's probably been touched on before but why no 3-under Hill shooters?
