Hi,
I am like my flute but think it’s tone tends to break a little bit to easy for my taste. From playing various flutes of my friends and at festivals etc I noticed that some flute definitely are more suited than others for specific ways of playing.
For example, my Pratten type flute from Lejeune has a very reedy and strong tone, but it isn’t as „agile“ as smaller bore flutes and the really ready over tonish tone breaks a bit easier.
I also noticed that most of my favourite players play Sam Murray flutes.
What would you say, which current makers have similar flute construction philosophies?
So, having a very hard to break tone and being really responsive.
Thanks 
When you say you want a flute that doesn’t “break” as easily, do you mean that when you “push” harder it breaks into the upper octave sooner?
If that’s the case, I’ll admit I’m somewhat surprised, as the Lejeune Prattens I’ve played have been able to be pushed pretty hard, at least for me. And I don’t think that the Murray flutes I’ve tried have been able to be “pushed” particularly more than other makes, maybe a bit more than average but certainly not remarkably so.
Murray’s flutes were a modified Rudall design, if I remember correctly. My suggestion would be a Lehart if you’re looking for a powerful Rudall-esque flute. I had one for a while and loved it, and it was capable of quite a powerful sound. I play sometimes with someone who has one and gets a cracking tone out of it.
Martin Doyle might be another one, or you could see about trying out one of Lejeune’s Rudall designs. TBH I’ve been impressed with his flutes when I’ve tried them, and if anything were to befall my current flute I might order one from him. I also quite like the Thompson flute I have, but he has closed his books for the time being.
I feel like the Hamys and Glenn Watson that I put my fingers on are able be pushed harder.
Not saying that the Lejeune can‘t be pushed very hard (in fact the very most flutes I try out are not able to be pushed as hard!). But the baseline of the Lejeune already has a lot of overtones? Does that make sense? I am not sure how to phrase it?
And if you push the flute in a percussive way, the tone gets too fuzzy for my taste and especially the D changes octaves a bit to easily. Compared to that, Watsons and Hammy that I tried feel very „bottomless“ and seem to have fewer overtones / a less ready baseline sound.
