I would buy the Gulls, just because I loved mine and so did everyone who rowed them, including Smoker owners. Custom oars are nice, but can be expensive. If you buy custom, this is the time to do it - so they'll be ready by spring. You should look into Blunt Family Paddles. Kenny makes sweet oars and engraves your name on them too! These laminate oars are lighter and stronger (I think) than solid ash. I personally don't like solid oars. Too heavy...

If I were buying oars today, and had the cash, I'd buy two oars from Kenny and two Gull whitewater oars for my spares.
If you're new at rowing whitewater you may want to take some used Craplisle oars out for a while, it's easy to break or lose an oar when you're learning. Also, use tethers! I've seen so many lost oars, even in flat water.
