So aside from the attributes of the 1099, would it be reasonable to conclude that a longer mast reduces yaw?  And reduces roll?  But the shorter mast pumps better with reduced pitch stability?  I've been using a 22.5" mast (or 57 cms) and have been yawing like crazy.  Thought it was just me.  Or is it?

Affirmative.  Going from 90cm to 68cm reduced stability in ROLL, YAW and PITCH. 

Because the mast is just a big fin you shorten the fin and you increase the tendency to YAW when paddling.  I was surprised by how much more YAW was introduced by the shorter mast but it made sense when I thought about it

PS:  My paddle is ~ 2" over my head.  With the 90 cm mast I would NEVER hit the foil.  With the 68 cm Mast I have to be a little more careful.  I have had 1 strike but no serious damage (yet).

You lucked out. Usually solidly hitting the foil with the paddle (actually it's more like hitting the paddle with the foil) results in an instantly busted paddle. The paddle is fundamentally fixed in the water relative to the foil motion, and can't be shoved out of the way--incompressible water holds the paddle in place. the foil is moving with the full force of all your momentum plus any wave energy and all that force is applied through a very narrow area (I'm playing fast and loose with the physical parameter units but you get the idea). If you do the math it's tons of force per square inch.

Oh yeah, I did that with my kujira 1210 twice in a row because the first time I couldn’t believe I had done it. And those tubercles punch good dents!

Was able to do some interesting (to me) gear comparisons yesterday in well powered 4.2 conditions at the Hatchery. The wind continues to outperform the forecast, hoping today is similar.

I'm 90Kg all up, 1099, 82cm 19mm, 420, short: first try on the Alu mast and it's a little more predictable in behavior than the (old) carbon 86. Won't stop using the carbon though. Can't say I noticed any difference in drag, of course there has to be at 14.5mm vs 19mm but in real world 15-30 and 2-3' waves it's pretty much irrelevant. Never had any intention of using this setup in this much wind but it does work 'ok'.

Switched over to the Go Foil RS 1300 at 105cm span, 8.5ish AR (specs are STILL incorrect on GF's page), 14.5L tail, same 100L board. Haven't used it in a while. Figured it might be somewhat comparable to the 1099. In the above conditions I can detect NO difference in glide but maneuverability and general user friendliness are well beyond the 1099. Logic dictates there should be some straight line advantage in glide to the 1099 but so far not seeing it. The 1300 gets going sooner as well which is handy. Pumpability is similar.

I definitely am spending way more time in the water and re-starting on the 1099, when it's 100+ degrees that is kind of an advantage :o

More testing today, if it's similar may screw them on the 70L board.

@thatspec might be the 420 tail holding you back

Yes, I hear the 1099 is heavily tail dependent.

Slightly lighter but still 4.2 conditions yesterday, bolted both setups to the 70L 4'9" board. Aside from the always tricky start of the -20L board, way more fun. More noticeable slight edge in glide going to the 1099 but so small that there's no real benefit to it in these conditions. Top speeds identical, 21.5ish. Never went in once on the RS 1300, 2-3 times on the 1099. Re-starting really drains the energy, especially so on the small board.

Perhaps in perfectly flat water I might be able to tell the difference between the 380 speed (arguably their fastest best gliding), and the 420 speed I'm using but not in active conditions with large areas of lifting and sinking forces (I've also tried the 350P with it). Big difference in the forces acting on our wings in wingfoiling conditions and SUP foiling conditions (a single nice glassy breaking wave). I think the 1099 is far better suited to the latter and /or downwind SUP foiling than wingfoiling (at least in over 20mph winds). It works and It's interesting. I really do like it but I haven't found it's forte yet for wingfoiling in the Gorge.

At worst I'll hang it on the wall as wingfoiling art 8).

I can tell you that for wall art foiling you’ll need at least the 450p if not the 475p tail. Don’t ask me how I know ???

Sure a 450 or 475P will work but one of the local sponsored guys said wait a couple of months as Axis is about to release an entire series of wall art specific tail wings. Each comes with an 89° shim ;D
