I spoke to them at one point about replacement props. The laydee on the phone was very nice and knew her props. She was however, surprised to discover that my etec 90s ran the same size props as your 115s. They do a recon range that are very good value - so good that if your dinged prop isn't too bad, you might consider one of them and save yourself the downtime. Get the dinged one done later.
I don't use the term "dinged", BTW...
I prefer "confirmed contact with an object of a Topographical Nature"
