If you have a chance please weight your plane, I'm curious about this.

I've only flown tail draggers so I'm quite used to bringing the planes in at about 20%-30% throttle until just over the threshold just a few feet off the tarmac.

At that point I throttle down to 5-10% and let the plane bleed off airspeed until touchdown, then go to full idle... and start trimming back to neutral idle.

Is this what you mean by "considerable"?

Re: C.G. basically yes. I have mine about 1/4" further back than recommended.
