Low C recommendations

I know “what whistle should I get” asked of 100 people tends to elicit 100 different answers but I’m hoping this will be specific enough to at least narrow it down a bit.

I’m looking for a low C whistle that’s tuned in such a way that it’ll play well with other instruments, not just itself (“equal temperament” is the term I think?). I’m partial to Burkes, but my low D takes a heck of a lot of air and I’m guessing a low C would be even more taxing.

What’s everyone’s recommendation? Are there good low C’s that are less lung-draining or should I get another Burke and hope that with practice I’ll improve in that area?

Price is a consideration but not a priority.

Thanks in advance.

Afraid that’s a misunderstanding of equal temperament because your need depends on what other instruments. Pianos, keyboards etc. are generally tuned to equal temperament whereas pipes wouldn’t normally be, and bowed strings, trombones etc. may have the choice put prefer to play just, Pythagorean or all manner of other scales. So there’s no one ‘tuned in such a way that it’ll play well with other instruments’ tuning.

Sorry, should have been more specific.
Pianos and guitars. A440.

I’m a Burke fan, but as you know the Burke Low D has a fat tube and fairly wide fingerholes and an unusually large appetite for air, and I can only imagine that these things are amplified with the Burke Low C.

My Goldie Low D has a bit narrower tube, closer-spaced holes, and superb air-efficiency, all these things combining to make it (for me) more ergonomic and easier to play. I would imagine that these things would make a Goldie Low C very attractive. (I never played one, but I want to get one!)

Also my Goldie has excellent tuning, just about as perfect as a wind instrument can be.

As has been mentioned above “playing in tune” is situational. I, like you, want all my instruments to be in tune to ET at A=440 due to the sorts of gigs I do. Though the differences between ET and JI are, in practice, more or less negligible, often being within the range that’s easily done with slight adjustments in blowing. JI enthusiasts can convert any whistle from ET to JI with two pieces of tape in a matter of seconds (throw tape on the F# and B holes).
