As you have probably gathered I love boating so its no problem to pipe up and say something about props.
If the props in a "less than perfect condition" it depends how bad it is as to the advise. The whole prop and edge should be a near the original as possible. If the prop has sustained damage to the edge it could be out of balance as well. For pits and abrasions don't be tempted to file or sand these as you will end up thinning the blade section and this will affect the strength of the blade and its performance, you would be better off filling it, so its a bit of a judgement call.
At RibEx next year, we can certainly give your prop a visual check for damage. As to making repairs on the stand, sorry this is not feasible as we won't have the specialist machinery there and would have no way of balancing the prop. If have any damaged props you can bring them with you, standard repair time is only 2-3 days so you can have it back in time for the next weekend.....
