Here are my favorites...
On far left, my old standby the Magnus 1, middle Silver Flame DS model (Also like the XL model), and on the right is a Pearson Deadhead in the wide configuration.
The new heads from Centaur do have my interest also, especially the real wide one, and I may have to give them a try... I also like the double bevel as I've had real good luck with it so far...
In a narrow 2-blade I like the Magnus Stinger but opt for the 4-blade configuration, and I also like the Steelforce heads which are very good also...
