It’s hard or impossible to tell listening on air. I’m left handed and use a straight key with my left. I learnt to paddle with my right hand including the iambic seven (C F K L Y Q and R). so-called squeeze mode.
I would urge anyone learning to use dual paddles to do squeeze mode, it’s more efficient (minimum finger/thumb movements). If I can do it with my ‘useless’ hand, so can you. Just turn the character speed down low, you will be error free in an hour or so. As for non-squeezing twin-paddle users, yes you can teach an old dog new tricks if you put your mind to it, I’m living proof.
Check your rig, Mode B is better than Mode A for squeeze mode
