...And doesn't dear Maxy show one common trait of a certain kind of poster...NEVER EVER admit you are wrong.
I suspect he had a little "liquid propulsion" when posting, and got confused between the 300ER (which can only have GEs) and the 200ERs (the EK versions of which have Rollers).
But admit it? Nope. Insult, bluster, mis-direct and simply ignore, but simply say "yes, that was my mistake"? No way.
Odd.....
