I have had a midtwist for a year. Before that I was on a jantex gamma 720 for several years and before that an epic mid. I did not have the luxury of trying the midtwist before I bought it. If I had, I would not have bought it, because I really hated the paddle at first. But I knew that it takes time to adjust to new blades, and since I have immense respect for Greg Barton, and great faith in him as an engineer and designer, I resolved to give the blade at least 6 months of exclusive use before casting judgement.
My main gripe with the mid twist was that the catch felt very hollow. With the gamma my catch felt instant, silent, and powerful. With the midtwist it was the opposite - late, loud, and weak. While I loved the firm power in the mid and late phase, and was very happy with the clean exit, I just could not warm up to the catch. I know Barton had said it would take a few sessions on the water to get used to the midtwist, but my brain is slow when it comes to learning new techniques, and it probably took me 3 to 4 months to fully adjust to the catch.
A year on I really like this paddle. My catch is still not as satisfying as it was with the gamma or the epic mid. I think that is an inevitable consequence of the highly twisted blade, as only half the blade is facing the correct direction at the catch. The trade-off is that half of the blade is facing the correct direction late in the stroke, which is in contrast to a non-twisted blade in which none of the blade faces the right direction in the second half of the stroke.
I am not faster with the mid-twist than I was with my previous paddles, and I don’t think I am more efficient with it either. What I am with the mid twist is less sore, and as a middle age paddler that is a big deal. Rather than having my bottom-hand shoulder shock-loaded abruptly at the start of the stroke (when the shoulder is in an extended and weak position), my shoulder feels protected with the midtwist. The force builds gradually and peaks when my shoulder is retracted into a stronger position.
As far as rough water, the mid twist has no bad manners. Like the original epic blade, it is forgiving of sloppy strokes, with no tendency to dive under the boat or twist in the water. The only downside in rough water I can foresee is that if your balance is really being challenged, and you take a panic stroke to save yourself from going in, you really want that catch to feel rock-hard the moment the blade touches that water, not midway through the stroke. Personally I have not been in that situation with the midtwist, where the softer and later catch fails to keep me upright. But I can imagine the midtwist being less beginner-friendly than the regular epic if the person holding the paddle is really flailing.
It has taken me a long time to adjust to the midtwist, but now I really like it and would buy another if I lost mine. In contrast to the experience reported by others, I have not experienced a performance benefit with the paddle. What I have experienced is less wear and tear on my shoulders, and at this point in my life that is much more valuable than a small gain in speed or perceived efficiency.
