i use ibd, and i think it is a fab product. but i would suggest that you should go for brisa. you have already trained with cnd with the l&p so it would probley be best to do the same with the gel.. from what i have heard it is a brilliant product and all the users of it say they cant fault it. i cant fault ibd either, but if i was cnd trained i would stick with cnd.
although im sure that there are people who will think im a loony for this, but i think it looks alot more professional if you use all of a particular brands products. rather than having signs up for loads!
if i decided to do a conversion, it will be for everything, mani, pedi, gel, L&p fabric#. then i will be offereing creative treatments and enhancements. rather than if i mixed and matched and i did, jessica mani, pedi, cnd frabric#, ons l&P and ibd gel.
although it seems a silly reason, but unifying (sp) everything looks professional!
