Very close to the original; I'd say over 95%. Smooth, mild and sweet bacco with hints of nuts and a balanced vanilla exhale. Basically a step up from RY4 varieties.

This is not my original work but the final recipe by the reddit user 'henrywinklersayehhh' on the DIY e-juice sub. After several iterations he updated a few months ago (www.reddit.com/r/DIY_eJuice/comments/52ga0r/recommend_diy_tobacco_e_juice_recipes_for_all_the/d7kk0in/?context=3) that the closest he felt he got in a year+ was:
TFA Western 7%
TFA Graham Cracker 5%
TFA Marshmallow 3%
TFA Vanilla Swirl 1.5%
CAP Hazelnut 1%
CAP Amaretto 1%

Having tried his first attempts (basically the linked 'adapted' recipe) and now this I agree with him that this is the closest to Eclipse and the best overall vape. As he notes, TFA Western + Hazelnut and Amaretto are key to the delicious main profile. The only addition I made was a drop of AP per 10ml to enhance the nuttiness, but it's not necessary.

Most other clones I've seen use a vanilla custard, probably since the description says "blend of Cavendish tobacco and sweet vanilla custard". But as with the Cavendish part being a crock (TFA Western is clearly the bacco base), the vanilla isn't really creamy/custard-like. VC doesn't fit, throwing off the overall profile. The Vanilla Swirl works very well imo and combines with the Graham Cracker to give the same smooth, sweet vanilla backnote. The marshmallow adds mouth-feel and sweetness. Though not exact, this definitely came closest to the original while also being the best overall mix in general of any Eclipse clone recipe I've tried.

I found that 2 weeks after power blending and 24 hours top off, the flavors have all settled / come out respectively.

*edit: While not necessarily closer to a clone, I prefer this variation even more than the original: e-liquid-recipes.com/recipe/1531818/Space+Jam%2527s+%2522Eclipse%2522+Clone+v2
