Yeah, going to 30° is like deploying airbrakes.  It feels much more gentle and smooth to me to go to 15° and slow down to the 55kt range, then go to 30° on final.  That also gives me a better glide profile if the engine quits and I have to make the runway.  It's just a style thing either way.

As for being slow at 15°, several weeks ago I flew alongside a friend in his Kolb at 15° at 50 knots for about 25 miles.  Easy peasy! :)

I would never try that around Mammoth at least not close to the ground.  

Yesterday we were in a box canyon indicating 75kts  at WOT and sinking 1,000' / min while pitched for steep climb.  Got this photo of Clarence King off the right wing while in this condition.  75kts is my minimum speed I'm generally at 95kts in a place like this so that speed was my cue to exit.

Doing 'everything' abeam the numbers allows me to control the nose for a few seconds at a single event.  Throttle adjustment, closing the throttle, 1st notch, 2nd  notch, pitching down all mess with the nose so I do all 5 at once and continuous control input isn't needed.

I understand why you do it that way.  But I'm done with trim and most of my speed right away.  If I'm using 15° I'm done, if using 30° I just go to 30 and repitch for final speed.

I didn't read all the post, but Andy has a spring in his control system that moves the stick forward, so he needs nose up trim at slow speeds to overcome the spring tension. Ed's CT is older and doesn't have the spring, so it gets trimmed the other way. And yes flaps will effect the trim.

So by the time you are on short final at touchdown speed, if you don't re-trim from your 62kt/30° setting, I suspect you need a good amount of back stick pressure into the landing.  If so, then we are similar.  We just make different choices on when & where to trim.

No I go into the landing with zero stick pressure.  I have zero from downwind to flare.

Does the spring affect things that much?  The spring tension is neutralized on my airplane almost as soon as I start moving on the runway.

Having flown both I would say yes. I didn't like the airplane with te spring.  My SW took very little trim movement throughout the flight. The airplane with the spring took a bunch.

Interesting.  I would say mine doesn't feel like it takes a lot of trim.  In cruise to make a slight change I barely move the wheel at all.  Of course, I'm used to it now.

I have considered removing the spring, I know others have.  But when I asked Flight Design they said it was an important part of the control system that was needed, so I left it alone.  I like how mine flies and I'm used to it.  Maybe Bill Ince and I could trade some time in each others' planes to see how the other half lives, since his doesn't have the spring.

You say that you trim full nose up for landings, and that is what I  saw with the one I flew that had the spring. All of the CTSW's that I have flown without the spring required very little trim change for landing, and certainly not full nose up.

Okay.  My instructor's CTSW was also a 2007 with the spring, and he taught me the procedure I have used in both his and my airplane:

1) Abeam numbers, throttle to idle; once below 80kt select 15° flaps and roll trim all the way to the rear.

2) trim stays full aft through the landing sequence, at all flap settings.  

Tom, do you have exy experience with an airplane with the additional spring that has had the spring deleted?  If so, does it fly like other CTSWs or differently?  Does the CTLS have a similar spring system, or are the very late model CTSWs an anomaly?

My customer who had the airplane with the spring has passed. The spring was not removed while he had the airplane. The late 2007 CT were an anomaly. The CTLS did not have the spring. When I am working in the pattern with the CTLS I don't normally adjust the trim. I normally use 15° flaps for takeoff and I hold forward pressure on takeoff until I go to 0° flaps. I reduce power to around 4500 rpm and trim for level flight. This trim setting normally yields about 60kts for gliding. After the first trip around the pattern I normally don't need to adjust the trim.
