Any thoughts on this Theo Wanne MP?

I just bought one to give it a shot. It does have a pretty dark sound, but it’s got a pretty loose fit on my neck (compared to my Selmer s-90) so I had to push it all the way in to get it to seal. Will try to give it some more playing time soon.

I think the water is the cheapest model. Here in the UK it's significantly cheaper than the others at sub £100, so it may be more affordable than you think to try.

I've not tried one though.
