Hi Kelly, I just stumbled on the O/L wrap discussion, and have some opinions on it all. Looks like you figured it out in terms of wrapping those Cobras, and the photo looks great.
I've rowed/wrapped O/L's for a # of seasons and just love the way they feather, friction-free, less crabbing, etc.
My technique is to use 3/16"nylon cord and soak it in water. Tight wrap on wet, leaving only 1/4" or so of exposed bronze at the O/L tips. I form a "loop" of several wraps at the ends by looping the final, 8-10 loops around a screw driver. I carefully pull-out the screw driver and feed the cord back through the loops and then pull it tight (so it all tightens on itself). This produces a shrink-wrap effect as the cord dries on the O/L.
After drying I melt the cord ends w/ a hot knife, followed coating the outside (only) w/ West Systems Epoxy.
The inside (oar contact) is treated w/ melted parafin wax, which of course is repeated, every so often during a 2-week trip, ie.: (above the Gorge and Lava Fallies.)
I wrap the oars with P-tex (ski base), or fiberglass seam tape, and stoppers made from wrapping w/ epoxy soaked, 1" webbing, and this combo has always worked really well, w/ rope-wrapped locks.
Cobra's design? I'll have to say I feel the main draw back is the hard, spiny ridge in the "saddle" creates a crabby, catchy pt. during the feather of the stroke, and I've never been impressed by this. -Guess I'm just a traditional, old-school, brass, open oarlock guy. My 2 cts. worth...

Andy,
I hear you about the ridge in the Cobras. A rat tail file and emery paper is my solution to anything not smooth on brass oarlocks. We give any new oarlock the emery paper treatment as they all come rough inside. Lately I've been buying used oarlocks from the Clacka dealer over the hill. He does a brisk business in fiberglass boats and always replaces the old locks with new ones when he turns a used boat around. Lucky for me cuz I get the used ones that have been polished smooth by the previous owner for a song.
Thanks for the great info Andy. I spent a day rowing a boat with the p-tex wrap on the oars and loved it. They were the smoothest and most frictionless oars I had ever rowed with. Almost too slick -ha! Really great combo. The lock was plain brass.
I've rowed the nylon line wrapped lock plus a glass wrapped oar for years. Also very slick plus there is no edge at the end of the glass wrap so the oars slide in and out of the lock nicely. The glass wears more quickly than the p-tex obviously.
Where did you find the p-tex wrap? Thats great stuff!
I ended up going for the leather wrap in a bare lock. -Mostly for looks and durability. They are pretty smooth but a little stickier than the options you gave. I think the next time I do oars I'll go with your advice and try the p-tex wrap. Thanks!
You should be able to get P-tex through a ski repair shop. Ask for the sintered stuff. Tognar Toolworks sells it online for $8.95 a foot but it might not be as wide as you want.

I've had oars P-texed at Humphrey Summit Ski in Flagstaff. Give them a call and I'll bet they could hook you up.
