yes, the quality of Series 7 have slipped.
I have tried all sorts and the ones I use now are D'vinci Meastro.
They hold their point, and the set I am on now have just lasted a full year!!! I am quite heavy on them, as I do scrub and dab
with them. They are however about to be replaced
No.1 and No.0 are the ones I use most, with a 10/0 for the finest of fine detail.They are slightly more expensive than Rosemary, but a lot cheaper than Series 7.
If you do have trouble getting brushes Mark, just let me know, I can send you some as ' pressies ' so it may get round the issue.
