Alternatives to munchkin weighted straw cup?

Anyone have any suggestions for switching away from the munchkin weighted straw cups? We’ve used them for a long time now. I’ve tried the 360 cup and two other sippy cups (a spill proof and a non-spill proof). My 2.5 year old doesn’t like the other cups we’ve tried. He’ll drink from them, but he doesn’t stay near as hydrated and he asks for one of his other cups the whole time.

I want to switch for two reasons:

1. I’m tired of washing those itty bitty straws constantly 😂

2. Our dentist recommended I try to switch him because he has a tendency to walk around holding the cup with his teeth by the straw. I remind him not to, but it’s habit for him and I find myself forgetting or not noticing. She did say he can still use a straw type cup (she actually said it’s better than a sippy cup with a hard spout), but maybe find one that he can’t carry around in his teeth. He does have a tiny gap starting in his two front teeth.

So…any have any ideas? I’m hesitant to move away from something spill proof because he tends to just drop his cup wherever he is and take off to do something. I’ve been having him pick it up and put it on the table when he does, but he’s not consistent enough that I’m comfortable using something that will spill until he’s consistently setting his cup upright on the table when he’s done getting a drink.
