Dexcool: Pro/con?

[only5kgt@uswest.net]

Greetings everyone,
Having just received the new afterrun pump (thanks again to
Chris Semple!) I am about to open the cooling system on
infamous 87 5kcst- when a thought occurred to me- is that
leave-it-in-for-ages Dex-cool coolant:
Beneficial/detrimental/same effect but more expensive/
as opposed to the good ol' green kind?
Am curious what the consensus on this stuff is.
Also, if anyone knows who can beat the dealer price of $70+
special order for the upper MC radiator hose, I'd be anxious
to know. (Part looks fine... I'm just in there already, and
it seems time to quit pushing my luck with the *final*
unreplaced bit of cooling system on this car!)

Oh... not to sound like that "quattros only" guy... but if
we all get talking about Torsens again (c'mon, geeeeez!)

Regards,
Rob
