I´ve tried it on a Boll Spirit and a Boll ZLF and it works great on both. Just cannot see why it gets more bad reviews than good, but then I´m probably the only person who liked Calibra Tour M?
The best thing to say about it is this: "When I use (no brand name quoted here) I play the balls to a variation of 10 cm left or right of the desired spot. With AIROC M I hit the desired spot - this rubber does exactly what I want it to". Not my quote, but from a friend who is in our national Top 150 and compared the AIROC to the selected stuff he gets from his sponsor...
