Cannot comment on the Carolina, but I had a brief paddle on the 2020 Allwater (blue nose) 25.5 and definitely a great race board for long distance open paddle. Also catches bumps.
I will beat somebody to it, but I am sure that there is also a One board that can be recommended in the forum :-). The Evo 2.0 looks like a very nice board for bigger guys (high volume) if somewhat less "flat racier" than the other two. But who likes flat water anyway
