I love Cloud sooooo much and can’t get behind BR540 at all. For the same reason as you, there’s just a weird dentisty/latexy feeling that’s so off-putting to me. I don’t get any of that with Cloud which is a mystery to me as I smell the latex strongly in BR540. I’d definitely try a sample of Cloud. It’s super long lasting on me too, I sprayed it about 12 hours ago and it’s still going strong! It’s one of the best fragrances out there for the price for me. It’s very sweet though, I will admit. But it’s unusual, I can’t really compare it to anything except maybe BR540 but even they don’t smell too similar to me.
