Hi hun, i do not think u can go wrong with either. I use both berins and perron rigot. Even though the same french man has introduced the berins range, if i have worded that correctly. I personally have found that the berins is a slightly improved range. I love the jet set as said above in the summer, as when it is hot your client through nerves or whatever seems to get hotter and hotter as well making the jet set fab. I also like the blue hot wax of berins and find applying it easier. But you may hate it. It is down to everyones personal prefference i think.
I like kim love the oceon blue and would not swap it for anything, but again i have had a few teething issues with this one in the cold weather with it setting up very fast, were as i here the berins does not set up. But there wax is more of a creme from what i have scene on lori dvd, rather than being more oil like like the perron rigot strip wax. So not sure if it will be as cost effective or as smooth to apply. But will let u no when i have tried it.
If i was u as you already are familiar with perron rigot i would pm collin on here and ask for a sample to be sent so u can have a try and see what u think for yourself, as honestly i think it is down to every individual prefference and what works best for them and their clients.
hth hun
love jenny
