I agree, sometimes "current trends" make a difference and sometimes not. And when they do make a difference, the human psyche is such that it's often assumed that the difference must be for the better in all scenarios, which isn't necessarily the case. Historically speaking, observation have often preceded understanding, so to simply dismiss observations out of hand because it hasn't yet appeared in a text book isn't always forward looking. Taking too many claims seriously though is also a problem, as it can lead to misconceptions and wasted time. Where to draw the line seems to be the hardest part, as different people's experiences and backgrounds will effect that decision. This can of worms has been opened too many times in too many other places though. If you don't believe something has any effect on you, then don't bother with it personally. But the individual who started this thread clearly stated that he wanted fast recovery diodes for an application. If he states that is his desire, then that is his business, and in experimenting he may learn whether the diodes will actually make a difference in his application or not. An opinion is fine, but making nothing more then derogatory replys simply because you're of a different belief are not appropriate. I don't know whether diode type will make a difference in his particular instance or not, but I have seen cases where it does make a very significant difference, and others where it hasn't. IMHO the question of what the aspects are that effect whether the diodes make a minimal or major difference (whether it be related to PC board layout or whatever) is where the real story is.

Nice post, agree to what you say. Indeed, it is difficult to separate the wheat from the chaff. Too many people avoid any intelligent discussion and just say "... but I heard a clear improvement. ". That of course kills all discussions, and I suspect that often it is just a made-up statement. That's anonymous internet for you, I guess.
