9' light oars
Hey Whetstone: Buy em! If you never have rowed with slender oars you don't know what you have been missing. Even in the Grand rowing a loaded 16' rig weighing 2,000 lbs. I always used 9' wooden oars. Back in the day we called them "Whippies", because of their whip like response when pulled on. With a loaded canyon rig it would take about 3 strokes to get the raft moving in calm water. The first stroke would merely bend the oar without moving the raft at all. However once in the flow, and using the current to do a lot of the work, they were fine. One can get some rapid revolutions with this type of oar. The technique to use is to keep your arms straight when pulling back using your torso, which will get purchase while also bending the shaft, and then finish with bending your elbows and pulling as the shaft whips back. You will experience a lot of power once you perfect this. In normal rivers like the MFS, Rogue, etc. the feel is sweet and delicate. They are graceful, which is why they remain the choice of Dory Boatmen. Frankly I am surprised they are not a prevalent these days. I believe they are not because of the costs involved in shipping shafts without removable blades.
P.S. If you don't want them let me know and I will take them
