When you get your 5 posts in, go over to the DIY section - there are posts there that have charts of ranges of percentages for flavors from various manufacturers. I don't think any of them are complete, and some may be slightly out of date, but people there can point you to the most recent ones and they'll give you at least a starting point to work from. Good luck, and have fun with your DIY! Oh - and welcome to the forum!
