Your comparison between the Onno and Epic vis-a-vis paddling is exactly the opposite of my experience. That may be because I have the Onno small endurance wing and a model that is a larger version of the same blade shape, and these are a bit different from the original Onno, but these paddles behave entirely differently from the Epic small mid and medium mid wings, at least in my hands.
There are so many differences, it is difficult to know where to begin. The Onno have round shafts, whereas the Epics I've used have oval shafts … this changes the feel a lot, and for me, the oval causes wrist strain.
The Epic blades load up immediately on entry, probably due to the pointedness of the tip. In contrast, the Onno blades load up much later in the power phase than the Epic, and much more in sync with my own power optimum during the stroke. This is probably due to a more rounded tip and wider belly (on the Onno blade... not on me). Some may prefer the very quick, solid load up of the Epic. It took me a while to get used to when I changed from the Epic to Onno, but now I much prefer the Onno's load profile and can paddle longer with less shoulder fatigue as the Onno power phase is in sync with my lats and hip power phase.
While the Epic has a very solid feel to the catch, it requires a rather precise entry to be efficient. The Onno is much more versatile than the Epic with respect to the optimal angle of entry. The Onno blades enter the water from a shallow stroke angle just as well as from a more upright stroke angle, and I find this to be a huge advantage in rough or very windy conditions. It is difficult to make the Onno cavitate (not sure that is a word, but I'm referring to the loud, "chunk" sound that a paddle makes when the catch gets water and air together)...the Onno blades grab water cleanly no matter how you jam them into the water.
Though I've not had the pleasure of trying a Jantex, the Gamma described above is the way I would describe the Onno blades. . . they don't dictate how you paddle in any way. I can grip the Onno very lightly because I don't need to control the way the blade enters, pulls, or exits. . . it just finds it's own way solidly and reliably.
Both exit the water cleanly, but again, the Onno is more versatile, exiting the water very cleanly and quickly irrespective of the stroke angle, whereas the Epic can feel as if it is dragging with too low or too high a stroke angle or too long a stroke. If you have Barton-like technique, that's probably not an issue . . . but I definitely don't.
Both are very well made and light. I give the nod here to the Onno based on fit and finish . . . never seen a split paddle that slides together so perfectly . . . though I don't think there is anything to complain about with the Epic. I have not tried the new lever lock on the Epic, but the Onno is superb - I can change paddle length very easily while paddling in almost any conditions.
Anyway... just my experience, and with a particular Onno blade . . . Patrick's newest design . . . but I find the Epic and Onno to be very different. I also used Knysna swing paddles for years and found them to be intermediate in their characteristics, though decidedly closer to the Epic than the Onno.
For what it's worth, all my PB speeds for 30 min, 60 min, and 90 min have been set since I've switched to Onno . . . doubt that it is due to conditioning as at 54 yrs, I'm probably on the downward slope of the fitness / strength curve.
Sorry for the long post - hope it helped someone.
