No doubt that is excellent advice. I don't do this for a living, now retired so the monthly price is a bit steep for part-timers and learners like me.
But, I can appreciate what a great tool L2 is. Just tying to bank a few wins to justify the expense.. and then again without it those wins to justify the exense may not come. So it's a bit of a catch-22, if you get my point :-) But great advice. I got the message! :-)
