From the reactions I’ve seen, I think the grapefruit is almost as diffusive as the chocolatini. I’ve gotten really good hits off of 335, most notably from a sourpuss barista at a coffee/bagel shop I go to pretty frequently. She never smiles or treats people as anything other than a minor annoyance to deal with, but the day I wore 335 in her shop, she was all smiles with me, complimented me on what I was wearing as well as the grapefruit scent. I told her I wasn’t sure about the scent, that I thought it might be too strong (true, I don’t like the grapefruit at all. I think it’s too strong and smells like feet), but she said “oh no, it’s just the right strength, and it’s lovely” with a smile and twinkly eyes.
That being said, I definitely think MX135 is better. The hits are more dramatic, the effects are long lasting, and I can handle the smell without the urge to check my underarms or my shoes.
