I use a variation of the NFSC (1/2 tsp. BP and bump up the vanilla - PinkZiab's idea sounds great!). I also add all-natural flavorings/extracts from Spices Etc and get rave reviews. I some in the dough and some in the RI (Antonia74's). I have used, and liked, Coconut, Lime, Orange, Cherry, Lemon, Pumpkin Pie Spice, Two Fold Vanilla, Raspberry and I love, love, love their Clear Vanilla. It is perfect for when I need a flavoring in my RI that will not compete with the cookie flavor or when I am doing white or a light colored RI (no color tint as with normal vanilla).
If you ever want to check it out, here is a link to the page on their all-natural flavorings and extracts:

The Flat Rate shipping will be the first option for shipping under the billing information and the 15% off will show up when looking at the summary.
I have had great reviews on the NFSC (use the best quality ingredients though), so I would give two thumbs up on that recipe. The flavors just give me more flavor options an my cookie friends who have tried them have been really happy with them too.
