Which plastic ski?

Ok I've narrowed it down to these 3 plastic skis.
I'm
169cm tall
72kg
I have paddled composite boats, (think uno max for flatwater and fenn xt for ocean) but that's not what I need. I need an allrounder boat. Think tight rivers, ocean and everything inbetween. I live too rural to test any boats. I'm leaning towards the nelo 510 because it might be a little bit faster and the seating position sounds good.

Any real world experience feedback would be great.

have you paddled any plastic boats...? after an Uno Max they just may feel too much like slugs ragardless of all round ability??

Hi waverider,

Yes im aware of the "slug" feeling, but thats' ok. I've paddled older finn endorphin and spirit prs. The goal is one boat that is the wrong tool for every job : )   I can only take one boat with me when i go away, so require a boat that can do some rough ocean and rough river. I don't really enjoy a lot of flat water paddling. I get bored.

I can’t speak for the other boats but I have really enjoyed my V7.  I am new to surfskis but have owned sea kayaks, rec boats, and white water boats in the past. The V7 is about as versatile you will find.  I use it here in Texas on our rivers, bays (with Oyster beds) and it is fun in confused sloppy waters of the Gulf.  It’s certainly not a performance surfski but it allows me to go about anywhere and have fun.  

I've only used my 510 in the ocean, where I enjoyed it a lot, but it does have an over-stern rudder option, which can be handy in rivers. It definitely feels like a surfski, albeit heavy and stable. In addition to the over-stern rudder, I'd get the "solid" rear hatch cover.

I've done downwind ocean paddles and mild white water river paddling in my Nelo 510. It's obviously not the best boat for either of these types of paddling but it's not the worst either. You would do well to take advantage of the interchangeable rudder though. The over stern rudder is pretty ordinary in any kind of following sea and you obviously won't be using the under stern rudder in white water.
I find that my Nelo 510 has a bit of a nose down stance in the water so it feels like it is pushing more water than it needs to. My other (single) skis are literally half the weight of the 510 so it was never going to feel fast but my carbon skis are nowhere near as versatile. Of course they were also more than double the price.
I haven't had any trouble with the fabric hatch cover but if I had the choice I would get a solid cover.
I had a Spirit PRS for a while. I still can't believe I put up with that thing as my only ski for over a year.
