Well selecting a cam should be more than looking at just one attribute. Just like a motor combo, you have to look at everything. I would never just pick a cam because of LSA or because of lift, etc.

As a general rule, a wider LSA will lessen the overlap, thus giving a smoother idle and broader powerband. But, with that said, a cam with an LSA of 110 could actually have less over lap than a cam with 112 LSA. You just have to look at the valve timing events.
