My understanding of physics says retentivity is the more important factor of
the two. Its pretty rich for someone to make note of the sparcity of
critical information when they have steadfastly refused/incapable/unwilling
to produce the mearest hint of information.

Why do you septics always seem to think someone is throw insulting comments
at you when others write in a nonambiguous and direct way?

How was that measured? By rubbing it on their chins? Sorry don't buy it.
Presumably you can quote coefficient of friction values for Panasonic tape

There you go we're back to square one. I have not seen any clear evidence
that one should use Sony EX over PR let alone use another brand altogether.
It seems like a reflex action to recommend a more expensive tape without
providing any data to prove it is a worthwhile endeavour.
The very fact that manufacturers' data is not easily obtainable is telling.
The next time I get a dropout in the middle of something important you can
say I told you so but until then I'll remain blissfully ignorant but
contented knowing that I'm not being conned into buying something that I
don't need.
