So would I. If I was just arguing for kudos points against a mate in the pub I'd absolutely say over 3.5
But betting is the only area of life in which I'm conservative. Especially on football.
It's a low scoring, low margin sport so I'll always err on the side of caution. & also years of experience has taught me how thoroughly unreliable Spurs are as a betting proposition. More so than any other team in England (weirdly the next worst are Arsenal)
So yes, for opinion over 3.5, for money being involved over 2.5. I'm happy winning less as long as I got a good value bet. Over long periods of time that always serves you better.
