I'm asking myself why you'd want to spend another $55 on a driver with a mere 2 yds(!) and .6 points advantage to your current piece? Each to his own, but...
Those are the numbers "on paper", but I think anyone who has used both would argue the L102 is much more forgiving and gets a few extra yards over what's in the specs.
I did skip the L99 and go from L96 to L102, and the specs on paper are very similar between all 3, but the L102 is just noticeably way better in every category over what it says on paper. Kind of like the pornography description - "I can't define it, but I know it when I see it". Could I still use the L96? Sure, but it's just not as good. It's not like the L97 vs L100 irons where there is actually very little noticeable difference.
Not knowing the OP's upgrade history, if he previously had the L96 and then upgraded to L99, that would be the one I'd be questioning in my head as to why. That one is kind of a wasted upgrade to me, knowing the L102 is right around the corner, so that's why I skipped it.
