Hi Cory!

I called Art today for just that clarification..(the clearest
and fastest water is usually at the head of the stream)

Better wingtips are needed on the straight wing, NOT needed on
the Warrior (tapered ) wing...

Aileron gap seals are recommended....

With the straight wing, the improvement in the flying quality
of the root sections carries some risk as the tips don't do so well
by comparison.

With the taper aka Warrior wing, Piper "fixed" the outer wing
panels, and they do just fine with the VG's installed..

Gap seals are to increase the roll authority at the lower
speeds capable with the VG's.

The guy makes sence to me... answered all my questions well
and to my satisfaction.Explained why he did the mods the way he did ,
did NOT make any outlandish claims, and outlined the possible
negative issues.

Looks like gap seals for ailerons and stab trim, and the VG's
for us..

New paint and interior 1st.

As I said, my personal experience on three different 160 or 180 hp's
stubby-winged Cherokees is consistent... they help a lot more than one would think at
the low end. Nothing substantial at the high speed end.

One other detail. I believe that AM said that they are NOT approved for stock
wintips. He said some aftermarked tips were necessary... whether it be hoerner style
or droop-tip... doesn't matter. They do the same (although the droop-tips on my bird
look a bit silly. Make it look like the "bat-plane"). Stock tips on the Hershey-bar
cherokees are awful from what he said.
