If you want counter weight oars cheap, ankle weights don't cost much to duct tape to your carlisle shafts, this is the set up i now have, being poor white trash from grand county.
I started out on the "your a pusy if you use counter weights, school", then i tried em out, and realized they saved wasted energy, and were easier on an already beat up body.
10-11' shafts, happy enough with the carlisles, would be nice to have blades that do not snag on oar tethers though.
If i had the money i would by a set of smokers.
