Anybody useing MSD 7AL-2 Plus?Thoughts?

I,m thinking about upgrading to the MSD 7AL-2 Plus box for the 2 step option.I want to have better reaction times seeing I have my 60fts down now.I like the idea of setting launch RPM,so I can concentrate more on the tree and not worrying about my tach RPM.Call me lazy,but have lost too many races due to bad RT.Whats your thoughts on the 7AL-2 Plus?Thanks.

I could be wrong but I think the digital 6 plus comes with a 2-step and is a whole lot cheaper. Not saying its as good a box as the 7AL-2 but...
