Questions relate to above ground drip irrigation...

Wondering if anyone can recommend the best compression fittings for 1/2" supply line with .700OD?

I've mainly got DIG Corp emitters and all the poly 1/2" line is DIG. I'm not sure I'm a fan of the compression fittings though.

Has anyone used them? I'd be interested in your experiences with or knowledge of them.

Can I substitute Rain Bird brand compression fittings with DIG poly line? Not sure if they are any better though.

I believe I read that Perma-Loc are the best fittings, but I cannot find them locally and don't want wait for them. Maybe I'll swap them in at some point once my setup is finalized.

Thanks.
