Whats Everyone Else Doing For A/C Refridgerant?

[1972C10]

I just tryed Did the Swap to 134a and my local parts house screwed up one of the crimps on my hose So i have to take it back but even when i had the freon at its peak before discovering the leaking crimp It really wasnt to my expectations

Now R-12 just isnt happening unless i walk over and get a case From Taco Town And i dont see my border jumping anytime soon

I have read about several other types but I was curious to see what others with similar trucks have been using with what kinds of results

I have an 85 With a belt setup off an 89 and that style compressor I have all new parts including a blue orfice Using ester oil And still didnt seem to cool as good as i remember those trucks being but then again not 12

So whats everyone else Using ?
