Well, the lower LO reeds are slightly wider than the lower reed on a
Hohner Classic/HM plate. However the upper reeds are slightly
narrower. LO reeds do tend to be a shad shorter, but not by much. The
lowest reed on a LO long slot plate is only about half a millimetre
shorter than the corresponding reed on a Hohner Classic/HM.  However,
the lower reeds on LO short slot plates (used on key of Db and above)
are actually longer than those on Hohner short slot plates, so "LO's
use shorter wider reeds" is not a very accurate statement.


Same again - some LO reeds are thicker than the corresponding Hohner
reeds, others are thinner, some are about the same...

I don't have the means to measure this objectively, but they do feel a
little different when you are working on them, I will agree.

There are several likely reasons for the longevity of Tombo/Lee Oskar
reeds. The biggest factor is the alloy used, but other factors include
a less destructive tuning method and a less drastic change in profile
between the tongue of the reed and the heel when compared with other
brands of reeds.

Yes - that was a deliberate part of the design.

Then there may be some good news for you in the near future. That's
about all I can say right now...
