Agree. But, most of us do use Wheeler and have been for long time.

I will be making the change for JavaTC soon following in TSSP's foot steps.
I hope others will follow. The
last testing I did with Les confirmed in my mind that Wheeler needs to be
replaced in order to gain a
closer approximation.

Take care,
