I2 and I3 for me. Bought them because I wanted to use on a current McDermott cue I owned. There were deflections comparison charts couple years back and they were real close to predator.
The people I have talked to that have tried unsuccessfully to use the Z shaft/smaller tip. Seems that they get to much unwanted ^^^^^ on the cue ball. Which tells me they are mishitting the cue ball. The larger tip is more forgiving but I feel I can aim better with the smaller tip
I find that if I practice with the I3, the smaller tip makes me hit the cue more accurately as any miss hit (not hitting cue in center, applying unwanted english) is magnified. I can then switch to the I2 and be more accurate. I have switched in the beginning of matches with no ill effects. They both have the same tips. I might think that it would help all to practice with a smaller tip and them move to a little larger one in the matches if your not controlling the cue ball well. . I wish McDemott would have the I series available in different tip sizes. I would probably pop for a 12mm or so.
