my guess is that they are all pretty aggressive choices for a beginner, Add that to fact that folks say some artificial courses are tougher than rivers (maryland, north carolina because the eddies are constantly in motion due to the walled in sides of the course) and the beat downs can be abrasive. What you can get is some quality instruction/lessons at a course venue and reliable water to practice on. . I would keep looking for a less aggressive boat and also consider easy rivers, using local paddling clubs, and taking private lessons in a river environment… NOC, Endless Rivers, H2O Dreams could all provide excellent private instruction in the carolinas.
If you tell us where you relocating to then we can give you more specific advice. For instance the wvwa is doing a beginner clinic on the weekend of june 9th and 10th about 3-4 hours from charlotte for a cost of $50.00. You can borrow boat for free- like a mamba or other similar river runner or creeker…
I believe that your boat choices and venue choice are better for someone who has already acquired the basic ww skills. If you want to learn rapidly, are athletic, and want a more aggressive learning curve then your plan will work well for you. It also helps if you’re in your 20s.
You do get points for already sea kayaking (of which I’m a compete novice) but found it to be a very different experience than ww. I like the fact you are embracing a new challenge, expanding your environment, and have a desire to paddle close to your new home. .
