A friend of mine have the blue one. I agree that the handle is very comfortable. Almost like the old Jo Shape blades that were more thin at the top of the handle i think. Why did they stop doing these? or atleast i think it is a different, it feels so.
I tried briefly the Appelgren and the Waldner. The handles are nice, very comfortable. The Appelgren is very playable, not extremely fast and nice touch. The Waldner is very springy, i didn't like it at all. I imagine the Persson would be even worse.
