I definitely would not say it is the only one. Are you really sure, OB, Fury, Jacoby, Poison (i know owned by predator, but not a BK), Tiger, Cuetec, Mezz, Lucasi and McDermott don't have one? A quick search on google, turns up the OB break is LD.
Also that chart you posted is pretty old if I recall. Lot of new breakers out since then.
You're right. The OB is the other one. I wouldn't say the others are low deflection, not like the Predator. OB is close though.
