I have heard that but also read that the newer IB's are a lot more stable than the first ones on the market, mine aren't very old at all.My CDC will discharge the pack and I can stop it at 5.4 which would .9 per cell. If I then tray them untill the light on each cell starts to dim it should be as close to equalized as you are going to get without a Smart tray (or I have been told by about 3 mod racers) will this hurt the IB3600's? I know the GP's can be taken to 0 or I have been told that. Just starting out in RC and don't wan't to wreck batteries as they aren't cheap.
It is true that newer batches of IB batteries respond well when you dead-short them (taking them down to zero, as you put it), much like the GP3300s. If you store them like this, it will reduce the run-time. Unless you are a mod or 1/12 racer, the lost run-time is not an issue.
Before the smart tray was released, most racers equalized their packs with a unit similar to the Zero-V, where you manually tray the battery until the lights dim. Some racers will equalize a pack before they store it, and then tray it an hour before they charge it.
