I own Bogart PH but have not tried Cristobal PH. BPH is very strong and sweet with mega sillage. I find BPH very linear throughout its progression and this not a good thing. I normally do 5 sprays of any frag. couple of weeks back i did 5 sprays of BPH and i almost suffocated. I sprayed it on at night and next morning about 8 hrs later i was walking around my house and my mum asked if i was going out because she could smell BPH about 6 feet away. So yes BPH will give u more than enough sillage so 3 sprays I think will be sufficient. I do feel that BPH even trumps Kouros in terms of longevity and sillage. BPH is quite a decent sweet tobacco frag but I feels its too strong and linear. BPH would have been perfect if they had toned it down a little IMHO.
During the first few wearings of BPH, the sides of my neck that came into contact with the juice became very red with a burning sensation. I remedied this by spraying further from the neck but there was still a slight redness but the burning sensation was no more. Sprays to the chest also caused redness but to a lesser degree. But it could be just my skin being extra sensitive to the ingredients.
