I shoot with a McDermott I-3. I prefer the I-3 over the I-2 because I like a smaller diameter tip (11.75mm vs 12.75mm). The small tip gives me a sense of geometric precision when I strike the cue ball. I borrowed an OB-2 for two weeks and didn't discern much difference between the I-3 and the OB-2. The stripped ferrule on the OB-2 was distracting to me and I didn't like it. I read enough negative threads on this forum covering the Predator (splinters, poor finish, warping, etc.). so I didn't even consider it. The Warranty and Maintenance Agreement on the McDermott I-series of shafts is outstanding. I have sent in my I-3 for cleaning, resealing, and a new Moori soft tip installed at no charge (did have to pay a Postage and Handling fee of $21.). A friend of mine shoots with the Tiger shaft and really likes it. I've tried it but didn't play with it enough to have an opinion. But, what I like may not be what you like - it's so subjective. Good luck in your quest for a good shaft.
