I have given some thought about getting a Low Eflat whistle. Any suggestions or is it better to stick with Low D. Play by myself so playing with others not an issue. Currently do most of my low key playing on a low F.
IMO,the Eb is more fun than the low D just because it is a bit sweeter overall.
The hole spacings are just that bit easier to manage and it has just a bit more volume.
I play in Eb all the time and love it.
