This one was more appealing to me (different color though, don't like the yellow) and wouldn't be interested in the nitro, a nice electric motor would likley speed her up a bit too.
Vario prop would also let you tune for conditions a bit better as well. Looks like a fun boat.
A cool side effect of using an electric motor, even if you flipped it, you could still get her back to the shore with the prop underwater! LOL!
