Mike,

Sorry for my slow speed, several urgent things came up suddenly

Yes, I like your slides very much and there are several suggestions
for your consideration

* pg 3, Big Puzzle: There is a significant disagreement between different
theoretical predictions.  BTW, most of quark models can predict masses and
have significant problem to predict widths

* pg 8: Pseudo-scalar meson Photo Prod, has 4 helicities.  It means that
it requires 7 independent measurements at fixed Eg and angle (or W and
t/u).  You can do so within a common phase accuracy.  To resolve
cos^2/sin^2 ambiguity, you have to have 8 measurements.

* pg 14: It seems to me that this formula belongs to the co-author of
your recent theoretical paper.  Max published it a while ago.  I am sure
that Eugene knows a ref.

That is all, Mike, by now
Igor
