Why would repining flanges help with double striking? As I mentioned earlier, and as was discussed in a previous thread, excess tension in the damper springs is a common culprit for double striking (especially in some new pianos) for exactly the reasons you mention below.

Have you tried reducing the blow distance to get more aftertouch? This was actually a thread on this list about a year ago, and some suggested that damper springs that are too strong could cause bobbling, although I've never been able to figure out why that would be the case (unless it just discourages the player from following through the entire keystroke) ... ------ Scott A.
