Perhaps not all stick dropping is the same? If you are dropping a stick due to a mis-executed cross-over, or because you weren't peripherally aware of the edge of your hihats and just missed. These things can be worked out through practice.
Or say you are going from an acoustic kit to an e-kit, or vice versa. Suddenly your high tom is a different height related to your snare, so there you go jamming the tip of your stick into your tom. It won't happen often, once you identify it and re-establish the muscle memory.
Are you playing primarily an E-kit? I have an E-kit similar in size to the one you have. The miniaturized feel of an E-kit, with its shorter reaches, means new opportunities to fumble around, that you might not experience on a full sized kit.
It sounds like from the reactions of the other members that you are just spontaneously dropping a stick while playing normally? Like here and there, like you never know what you'll be doing at the moment it happens?
Tough crowd in here anyway, lol. I occasionally drop a stick in the shed sometimes. It's usually me running into myself trying to layer fusiony patterns. Or when "transposing" new ideas between the acoustic and electronic kits.
Having a light grip is requisite for really opening up your playing. Having a light grip also mean yes, if anything unexpectedly interferes, makes contact with your stick, it's likely to be knocked loose from your grip. This is 100x more likely to happen playing busy music, rather than straight groovy grooves.
Crash cymbals can snatch sticks away too. Dropping sticks is frustrating
, I wonder if this second "drop" was intentional, lol.
