Has anyone used the Duracool R22 replacement in the rooftop AC? What were the results? How much goes in?

You must have missed the response to the previous time you asked... Follow this link to the July forum thread: GMC Forum
And from the original thread:

I finally decided to try this out as my roof a/c never cooled much since ownership of my PB (since 2004).
Took off the shroud and found that the unit had a clamp on service port on the suction line. Vac'd the unit for an hour, broke the vac with R22a (a.k.a. R290) then vac'd again for another hour.
Charged the unit with 12-14 oz, pressure settles down to 29-30 lbs on the R22 scale of the gage.
The unit can really chill the PB, outside is 86F and in the sun... why did I wait to do this???
