Thanks. My understanding, and I'd love to be straightened out if I'm wrong, is that most LM and/or simulators record backspin. I have seen a few that calculate and display sidespin as an actual number but not very many.
Further, I seem to recall reading years ago that one of the reasons 3w is recommended for many high handicappers is that the extra backspin generated somewhat counteracts the side spin imparted by poor club path and face angle (ie, by the typical 'pull-slice'). In essence, the 'resultant' or 'effective' spin is less 'off axis' when pure backspin is increased. This is why its hard to hook or slice the snot out of a short iron (although as Bubba showed at Augusta, it can be done).
I could be botching this recollection or the origninal writer may have been out to lunch. If this is a gross conceptual error I'd love to be educated.

Very interesting! Anyone have some info on this?
Great point.
Anyone?
That's correct. The higher amount of backspin counteracts sidespin so you usually need more side spin (or the face needs to be more open or closed) in order to get the same amount of curve. That's also why usually it's harder to hit an 8.5* driver straight than a 10.5*. The 10.5* will usually back spiin more so sidespin doesn't take the ball so much off line.
Of course the holy grail is low back spin with low side spin (partially from high MOI?) for a given swing speed for long and straight drives.
