the best speed brake...
...is a slip  They're fun and very effective.

Jeremy, What a FUN phase of flight! Does anyone do the slip on a regular basis in the 9A? Is it a good speed reducer?

I slip occasionally. I wouldn't say it reduces speed, the plane will in fact speed up if you let the nose down. But it will add drag and steepen the angle of descent.
What's working best for me is to keep the nose high, looking for about 60 knots on final. The plane will finally slow down and descend. Slip or S-turn as required. Power is at idle for most landings.
Power off stall speed with full flaps for my plane is 42 knots, so 1.3Vso is 55 knots. Speeds like that or lower are required to have any hope of being close to the quoted landing distance, and would be necessary for any real short field purposes.
The hard part for me was that transition training taught me to keep 90 mph on final (more appropriate for a RV-7A, even then still too fast). The instructor was being very conservative.

High AoA is an effective speed brake on the 9. There is a fairly long thread concerning the -9 landing technique, and this one is discussed heavily. I sometimes bring the nose up right on the burble and the airplane comes down like a freight elevator. IIRC, this was considered borderline reckless by some here, but it works for me.

Not a -9A but a -9, and yes, I slip mine regularly!
As ToolBuilder said, the landing technique has been discussed at length.
I get my FP RV-9 slowed down before the pattern, drop in all the flaps abeam my touchdown point and trim for 60 kts (heavy) and 55 kts solo/light.
Once established at that speed, I fly the entire pattern w/o touching the trim or flaps. Strong winds, crosswinds, whatever are all flown the same way. Expect that I may use 60 kts, regardless of the loading.
Then I can use power for distance and pitch for speed. Simple as that.
(Yes, I have landed in very strong crosswinds with full flaps, like 35 kts direct crosswind, in my taildragger -9 using the above technique. The -9 is just a great flying plane!)

I've 400+ hours in RVs but only had a small amount of RV-9A time when I bought mine. I did two landings with the owner before I actually paid for it, and the landings went quite well, so I knew I was safe... as long as I acknowledged my limitations in the new plane. After 20 or so landings, and getting the idle speed adjusted back down to where it belongs, I'm now relatively proficient in the RV-9A. However, there were tricks for doing things like keeping the cylinder head temperatures under control on climbout (I do climbouts at 120 knots, traffic pattern at 65).
As far as traffic patterns go, time in other RVs is of little benefit when transitioning the the RV-9A (no opinion on RV-12 time). The -9A with a fixed pitch prop doesn't come down very steeply. Like other planes, the -9A is pitch sensitive in the flare, so fingertips and finesse are the order of the day.
I was unable to find a RV-9A instructor, and have not applied for an LODA to give dual in mine (I may or may not), but would be happy to chat with you on the phone if you're interested. And don't forget that the EAA Flight Advisor program (I'm one) is established to help new owners' first flights in new (to them) airplanes.

Ron,
I am based in Salem now. If you want to do some flying message me. You can log all the time, including the landings. I can sign your log book.
I slip my -9 all the time. It's not nearly as effective as other types of airplanes I have flown but it gets the job done.
