Berdyk is 6'4" tall, so has decent leverage.
Isner is 6'10". Don't ask us to serve just like him. While his height is only a foot more than you and I, his reach could easily be two and a half higher.
Milos is only 6'5", but his arms are the longest for anyone nearly his height.
If you're still suffering from pain of TE, stop playing, heal up in a month, then resume play in a controlled enviornment.
