Right know I have three Classic + shafts. One has an Ultra skin med on it. It's hard to keep the ferule clean. It's keeps getting a brownish black sticky residue on it. The other had a Kamui black med. on it and the same thing was going on. The last one still wears the Tiger Everest tip on it and it leaves a light brown color residue. My question is is it the tips or are the OB ferules hard to keep white. Also thinking of trying a Tiger Sniper on the second shaft to see how it plays. Any suggestions would be great. Thanks. Michael.
