At 60kts we climb out at 1000fpm, and the nose is pitched
up a bit too high and the dash blocks the view of the

I used to feel that way in the PW5 until I realized that I was trying to keep the towplane on (or near to) the horizon. The climb rate and angle is so great in a light glider behind a powerful Pawnee that the towplane should be nowhere near the horizon! You are probably WAY above the path that the towplane took. Drop down until you feel the slipstream, then come up a little. Now the glider's nose won't be in the way.
