tink As a ST holder in Y20 i've thought the atmosphere has been quite muted so far this season, for various obvious reasons.
For the Everton game I was sat in the South Stand (so my cousin could sit with me) and the noise coming from Y25 was great. I wondered at the time whether it was always that loud, and it just didn't carry to Y20, or whether it was better than usual on Saturday. Pleased to see that it was the latter, hopefully that will continue in future games!
It was certainly the best atmosphere so far, but not by a great deal. I think the acoustics in that bowl are pretty shit to be fair.
