did you re-pitch the prop? When I modified my 140, I re-pitched
to the 60" prop, gained cruise speed and climb rate.

You gained climb with a longer pitch? that sounds odd.

There is always the AMR&D Prop tip mod and repitch... I've heard mixed
impressions about that though...

Save it for next year.

But... but... I like my toys!

But it adds weight, taking away from the already constrained useful load

That's very true... Fortunately my bird is a '67 with no options (no
toe brakes, simple vfr avionics) so she's rather light as Cherokee
140's go....

Granted... I know I can eat through that extra window _really_ quickly.
