My instructor pointed this out to me: the 150 stall speed between 20 and
40 degrees of flaps is only *1* MPH!  And for that go-around, those
extra 20 degrees hurt enormously.  That's why he teaches everyone to
only use 20 degrees max.  I learned in a 172 but recently got checked
out in the 150; that's when I found out.  Makes perfect sense to me.  He
also said the 150 just barely will climb with 40 degrees of flaps; if it
is near fully loaded, it won't climb at all!

All true, but sometimes you need the extra drag, like in an engine failure
landing in a short field, and you need to drop in steeply to avoid an
overshoot.  My normal C150 landing use 20 deg, but I practice with
40 occasionally.

To provide perspective, with him and me and 9 gallons of fuel, the 150
was at gross of 1600 lbs.  We landed several times at Moontown, a 2000
foot grass strip and if memory serves, stopped in about 800 or 900 feet.

Most grass strips stop you faster because of the drag on the tires.
Unless of course it is short wet grass. What was the height of the grass?
