Hi, I'm an oboe player myself did grade 8 oboe earlier this year now working towards DipABRSM level.
I have used Winfield reeds from the start when I first learnt the oboe but now I use the professional ones I have found myself most of the time the reeds are good, occasionally can get some dodgy ones.
If you get the reeds directly from Mr Winfield and you are unhappy with them he will normally replace the ones free of charge.
Link to his website if you don't have it already is:
