I am not a fan of Cowdery doing the commentating for all of the reasons discussed on here already. It's notionally fine when he's doing the interviews for the website (although he's no Andrew Neil in those, tbh, and always sounded terrified of Adams), but a commentary is different. We don't want pro-club soundbytes - we're supporters already, so the proselytizing is wasted on us - we want a reasonably accurate portrayal of what's happening. By all means be pro-Argyle when we do well - Sparksy's enthusiam was great - but don't dress it up as something else when we don't.
Combinations of Drew, Gritton, Errington and Fox have all worked well this season.
