I hadn't noticed you had the electric nose lift.  

Be VERY sure the nose wheel fork pivot shaft is tilted aft at the top. 
If it is tilted forward at the top (not enough strut extension) the fork
will be prone to flutter and I'm sure you've heard of nose wheels coming
off and damaging the prop.

You can easily see if the extension is taking the nose "over center" by
laying your hand on top of the canard while somebody extends the gear all
the way.  You should feel the canard go all the way up and then come down
slightly showing the mechanism is actually over center.  If the canard
doesn't go down at all, then the mechanism is NOT over center and the
electric lift is doing all the work.  That can be overloaded in a hard
nose wheel touch down.
