I need to replace the ferrule on my OB Classic + Shaft. My cue man said he could use Titan, Juma, Antler, or the original OB Ferrule. He said he would have to contact OB to get there Ferrule material. He has the others in stock. Any recommendations on what I should have him use? And also what length should I have him do? He said the Antler would give the hardest hit. The Titan would be the most resistant to staining but can be brittle. He said he personally likes to use Juma for the best hit. Thanks Michael
