Excuse the image of the pressure gauge and compass dangling. Normally that should be clipped. However, it did give us a sense of the accelerations and velocity of the diver. By the way, these pics were at Waldo Lake in Oregon. A cold high mountain lake,, lake surface at 5,400 feet elevation.

Interesting size comparisons. I didn't take any pictures yet, but I did run into the garage to do a quick comparison. I didn't really notice a difference in size between the XL and XXL. The picture somewhat supports that the difference is minimal. Both fins exceeded the length of the TrueFin in the center, but the edges were about the same length.
I'm curious if the TrueFins will have different lengths based on size.
No, very little if any difference in overall length between the different sizes of Truefin... The difference will be the foot pocket of course, but also the overall width of truefin will change depending on the size. For example the medium Truefin is about one inch narrower overall than the overall width of the large Truefin.. We wont be producing the medium Truefin until January 2024.
A couple miscellaneous points..
When installing the spines, install the hash marks III on each vertebrae adjacent to the hash marks III at the bottom of the Monprene rail. That is mentioned in the instructions.
With regard to the length of Truefin of different sizes, the reason the overall length will essentially remain the same between different future sizes is because the same spines will be used for all sizes of fins, and also the heel strap posts (non-proprietary, 20mm flange, 13mm throat) need a minimum distance between the post and the spine so the spine can be withdrawn, while the post needs to be the same distance for all sizes from the rear side edge of the foot pocket to accommodate the heel strap buckles or brackets - so we can not make the fin shorter.. However, for larger sizes we could make the fin longer while using the same spines, but at just under 24 inches it is long enough, and has maneuverability and high thrust.

I had to post this from the Bali video above...
As I've mentioned before, I am not a scuba diver, but I suspect this ocean current is exceptional.... This diver is just drifting with it, but this is an example where there are situations when you must have thrust capability.

@scubadada, I'm looking forward to your review of the fin. I understand you dove them several times on your recent FL trip.
I dove mine again the other day at the bridge. They are great fins for doing photography. I'm almost frustrated when I dive my DiveRite XTs.
As I dive them more, I have the issue of having to use the large springs for my long photography dives so that my feet don't hurt and having to use the medium springs when I got on a boat, so that they don't come off my feet when I jump in. I think the medium springs would be fine if the foot pocket was just a little larger, maybe 2-3mm in width and/or height. I didn't bring them out on the boat yesterday because I had so much gear prep to do, and swapping springs wasn't on the priority list. With how the currents were, there was a lot of surge, I was wishing I had them.
