I think it would be helpful to have a list of single flavors from different vendors that work well right off the bat for new DIYers. It might help them start out with a winner and not get so discouraged while they're learning.
Here's a few I think are good standalone flavors.
Capella:
Chocolate Fudge Brownie
Cinnamon Danish Swirl
Dutch Chocolate Mint
Chocolate Raspberry
Boston Cream Pie
I do recommend adding EM for a more full-bodied mix and/or extra sweetness.
Start by adding 1 drop to 20 drops of no-nicotine PG/VG (for 80/20 you would have a base of 16 drops of PG and 4 drops of VG. For 70/30 it would be 14 drops of PG and 6 drops of VG.) That gives you roughly 5% flavoring, 2 drops of flavoring would give you roughly 10% flavor, 3 drops 15% and 4 drops 20% (thanks Str8V8ping for the easy calculations).
Some prefer to let their samples sit for a few days to meld the flavor. Since it's just one flavor I go ahead and test it knowing that it could change with some steeping. This will give you an idea of the flavor but most of the time it will get better and stronger after a couple of days, especially chocolates and creamy flavors.
When you find the % of flavor you like you can make a 5ml batch using one of the calculators to get the %s. Using a 1ml syringe is the easiest way to get accurate amounts in small batches. 10% flavor would be .5ml flavor and 4.5ml (nicotine, PG/VG) base.
