Hi all!
First of all shame on me, I didn't read this article entirely (one of my very very bad traits ;-) ), thanks very much though for pointing it out. Given the very good arguments I think it's better to create subclasses. Also thanks to Mike I figured out how to easily create those subclasses. Very cool!
Cheers,
Chris
