Hello

After having great success with the Irvine 40D. I am looking for an upgrade replacement.
That "fits" in and replaces the Irvine 40D I allready have with a little extra.

Of course with a Davis diesel head. But which one will it be ?
I get my hand on a PAW later on.

1. Irvine 53
2. OS 46 AX
3. MVVS 49

Any advice on performance, consumption, reliability ?
