There's just so many arbitrary classifications used by everyone in this thread, with regards to pitches, bowling types, and plain ignorance of match contexts, which is going to be the main determinant of what Sobers bowled. It's made to sound in here as though, "Oh, pitch looks a bit dry, better play Sobers as a pace bowler/spinner then."
If you've used three pace bowlers, and they haven't gotten a breakthrough, some days you'd use Sobers as a spinner, because they haven't looked threatening and you want to change things up. Another day, you might use him as a pace bowler, because you think that your quicks haven't actually bowled that well.
Who knows, maybe some days he bowled spin because he'd reeled of a ton earlier that day and couldn't be stuffed, or maybe he bowled pace because he felt like hitting someone in the head? There's so many sweeping generalisations over a 20 year career it just seems ridiculous.
I'd include him as an option in my all time Team, not just because of his batting but because it allows me to keep a consistent team wherever I went - an important facet of any successful team IMO, and the fact that he's the fifth bowler means that he won't be doing a great amount of bowling anyway, and if I can unleash him in bursts as a pace bowler, or to play a role as a spinner where that's more appropriate, it brings as much as any number 6 or 7 can reasonably be expected to fulfil with the ball.
