Grafton + TH & C alto || Naked Lady 10M || TT soprano || Martin Comm III
Is a 2 1/2 reed on soprano inhibiting my intonation issues?
I'm not sure what you mean by inhibiting. If there are issues, is it good to inhibit them?
Anyway, if a 3 is too hard, then it's too hard, don't strain to use something unsuitable.
A 2.5 should have no problems with those mouthpieces, and to be honest, a certain reed strength (especially something as bog standard as 2.5)has little bearing on intonation anyway.
