Which Al AST is the best?

 

That's kind of a subjective question.


My Pettit Al AST works pretty well, I guess. How do I know how well it works? I don't!

Some folks just eliminate it. It's cheaper, and I haven't heard of any complaints.

 

Yeah, I don't think there's one that's better than another. None of them leak and all of them are better than the stock plastic AST. Get whatever you can find that's used & cheap with a good cap.

I had the Pettit also - it fit good and... uhh... didn't blow up, so I guess that's good.

 

Theres a whole recent thread about this.
