If they were competing against Grimethorpe, Fodens, Carlton Main, Fodens, Fairey, Leyland, Flowers and Desford you might have a point, but they're not. On paper they are without doubt the form band in that particular field.
However: Two-legged contests can be weird, especially if the adjudicators don't like, or get what you're trying to do with, the own choice piece. In theory they make a shock upset harder, because the "weaker" bands" have to outplay the "stronger" bands twice in a row. But bands that don't play a "known" piece, like "Pursuing Horizons" due to be one of the own choice selections at the weekend, or they play a classic like "Contest Music" (also on the agenda) but not so well, could come a cropper. If Paddy F was still around I'd be tempted to have a cheeky flutter on Hepworth who are likely to be bang tidy with Mr Fowles in charge (as they were at Bradford when they beat BD by a place), or GUS looking to give John Berryman a decent final season send off.
