PS What is all your view on and experience with paddle blade profiles in general?
Different paddle profiles have their own benefits/disadvantages relative to your needs as a paddler. Remembering that for over 95% of distance paddlers, the first thing to suffer as you fatigue is technique and some paddles get an unfair wrap as a result.
Concave faces are excellent for power at the catch from the get-go, but if you choose too large a size you can fatigue quickly if you don't have the physical strength/technique to maintain the "instant" grab. This is one of the reasons that Starboard changed there tip shape in the evolution from the Bolt to the Lima. The narrower base tip of the Lima moderates catch compared to the aggressive square tip of the Bolt, making the Lima a less tiring blade for most users. I still feel a concave face like a V-Drive/Lima/Bolt is the most efficient for paddling but you need to get the blade size right or it's a slippery slope for the smaller-shouldered paddler. I believe JP Australia also make a concave face blade.
Dihedrals are primarily there to help centre the blade as you pull through the water. This is a benefit that comes into play more as you fatigue and your technique suffers, thus helping maintain a straighter pull with less concentration. A "stronger" paddler with good technique is technically less reliant on having large dihedral - but they still may choose that style because of the "feel" it gives. And "feel" is an intangible that differs between paddlers but is a very important element.
Most paddles like the ONE, 425pro, Fanatic, Ke Nalu and the like, keep things simple with regards to design and that is the secret of their success. Rounded profiles, softer contours making ease of entry/release, with differences being in construction, face angle, tip curve and other small nuances to vary how the power comes thru as you pull thru your stroke. These are probably less fatiguing over time than concave face blades and also tend to have a nicer "feel". Great for older paddlers or those with shoulder history.
Often if it feels good, it is good and you'll paddle better. That is why you should narrow down your choice with the advice of others relative to your personal needs - but ultimately try and use a paddle before buying it if you can. With regards to distance paddling, the importance of getting the correct paddle is often understated with most of the focus on the board under your feet. Remember you will use the paddle up to around 3000 times an hour when paddling

, and while your boards may change the paddle usually doesn't.
I apologise if I have left out any paddle brands, I have merely mentioned what I have experienced in my years. I have been involved with paddlesports most of my life and getting the paddle right has always been important to me. For disclosure I must point out that 425pro have been kind to me with paddles, but there are many great choices out there compared to when I first started.
Keep paddling
