im not a troll.. or a splitter ... so i can tell you 15X21 is the best 15 aventus I've ever tried... i pretty much have al the hard to get batches (except never cud get 11X01) but this bottle i got today is still performing... one spray on neck, one on forearm, and one on shirt... i should have not did the shirt.. so far I'm in 7 hours in .. still projects.. this is something that Q01,U01, or U11 could not do.. (but to be fair U11 does project at first.... but dies down for me 4- 4 1/2 hours but to be fair its a decant.. not the bottle.. bottle lasts 6-7 hours then dies down... Im not here to hype the batch .. I'm not selling splits.. all I'm doing is telling my experience ... 15X01 was very good.. but this 15X21 ? i think creed is finally getting it right...
