Thanks Dave, did you order them directly or through another retailer? They indeed look like an improved Rovner, many of which aren't bad I might add.
Thanks Dave! very helpfulI got mine from a London retailer T W Howarth https://www.howarth.uk.com/products.aspx?id=113&url=saxacc.html but I had to order in a few of the 'S' and 'L' versions as they mainly have the 'M' version.
Thomann also stocks them https://www.thomann.de/gb/gf_ligature_gf_06s_gd.htm .
Be a bit careful with sizing, as I have found that, for instance, GF claim the GF-06M fits a Selmer mouthpiece, but it doesn't really.
Alos, FWIW, I didn't like the 'Maxima' version - too fussy.
