Thanks for the great feedback. I just mixed using the same base using 2% FA Banana and replaced Hazelnut with 1% FA Walnut. I guess only time will tell how it turns out.Well, I made both, mixed by weight and steeped for a week. Surprisingly, retaining the hazelnut made the bilberry stand out more (Mixed at .5% in both). Losing the hazelnut made for a much more mellow vape but both were very nice. Whether the Hazelnut would have the same effect on all fruit flavours remains to be seen.
