I would like some feed back on Slick mags, at altitude, pressurized,
operating LOP.

We have had to replace a lot of slicks with Bendix 1200s when we do turbo
conversions for the Bonanzas.

Some people continue to say they get good results with the pressurized
slicks at altitude.

But I am never sure that this is done when well LOP, or not.

Any good hard feed back would be appreciated.
