You don't have to use just one supplier. Most of BCN's oils do well in soy. If you go to their forum you will soon find out which ones are REALLY strong. I use probably 80% of BCN's oils, simply because I get my EZSoy from them and I try to use their oils as much as possible to save on shipping and for simplicity. I've found the following BCN FOs work well in EZsoy: Lemon Pucker (SUPER STRONG!) Creme Brulee (AWESOME!! SUPER STRONG!!) Spiced Cranberry (WOAH!!! Super strong and GREAT seller!!) Vanilla Velvet (Moderately strong, but the best vanilla out there IMO) Wildberry Zinger Tea (SUPER STRONG!) Cupid (Bubbles N Lights Line, my BEST SELLER, VERY STRONG) Twigs & Berries (run you out of the house strong!) Blueberry Muffins (super strong, not my fav oil though, didn't sell well) Country Berry Hotcakes (very strong, again not my fav) Sandalwood (VERY STRONG! Nice in cp soap as well) Mulled Cider (moderately strong) Mac Apple (WOAH... VERY STRONG) Pumpkin Pie CO (VERY STRONG!!!) Verbena Berry (AWESOME.. VERY STRONG) Grandma's Kitchen (best seller, VERY STRONG!) Lavender (good, herbal lavender, VERY strong!) Granny's Pie Crust (Bubbles N Lights, awesome scent, bugger to wick) Vanilla Grapefruit (Wick Your Wax, VERY STRONG but doesn't sell well for me) OK getting tired.. there's more but I am beat! HTH!
