Alan,I see you use the modern pronunciation and I am wondering whats the difference between that and Buth's system?
Trent, There is not a lot of difference, the main difference is the eta. But I prefer modern a bit more than Buth's. And I prefer Buth's a lot more than Erasmian. See Buth's excellent discussion here:http://www.biblicallanguagecenter.com/wp-content/uploads/2012/08/Koine-Pronunciation-2012.pdf
