C2 Collars and Dreher Oars?

[Nosmo]

We have some older Dreher and C2 oars with white collars. I assume I can use the new green C2 collars on both brands. Correct?

Have you tried? Do they fit? If so, then yes. If they don't fit, then no. Long ago when I was wondering if a program would compile, a friend said "Ask the computer - try it - if it runs, then it works."

If the C2 oars have the sleeves with the insert, just swap out the insert: much less expensive and solves any wear issues...
