Nice shots!
Regarding boat handling it does look like first race of the season :)

First race of season, biggish winds, new protos...
Yep, why bowsprit so high or am  I wrong.... you need to align forces between pointy end and point of fixation on boat... see 677....

Placed your other video here instead of new topic,

Sea the boat in action with the final bowsprit fold

I noticed that too. My coach was a tornado sailor and he was horrified to see how hight the tack was on my kites. We have since move the sprit down and it has made a big difference.

My compromise was, point of sprit as high as the stanchions.
I think carbon sprits can be easier held higher. But the alu tubes are a bit light for that.

Are you talking about this from a performance point of view (i.e. direction of pull, shape of kite), a safety point of view (i.e. lifting bow out of water), or a gear failure point of view (breaking pole) when you talk about the "big difference" of moving the tack down, or the "compromise" of having the tack at stanchion level?   

Also, my fractional reacher tack flys from halfway along the pole which scares the sh*t out of me when I think about the bending moment that applies to the pole.  Does anyone else have this setup?

GLT, most people who fly sails from mid-sprit tend to use some type of strop around the pole that captures the bobstay and both guys. When you do this, the sprit goes down because you effectively shorten the bobstay. I just used a spectra loop that was just big enough to luggage tag around the sprit and stays, leaving a small loop to tack the furler onto.

Only for breaking... for shape you change the tackline tension.
In light winds you can put it higher, but that is not needed because you want it down then.

And if you loop it as phoenix says, you get the compression again in the right direction...
You do then not pull in the middle. But the forces get redirected by the ropes.
I only did this with Code Zeros. Then I really tensioned both guys. Under spi I only tension luff side guy, lee I give some freedom (15 cm or so) so you do not get shock loads but the sprit ccan play around a little bit.

If you stuff the bow, a low sprit can be a bigger risk, but if your Spi is then eased on the tackline, it does not catch there anything then the sprit in the water.  BUt easing then means not sailing as high as you could......
