I don't think the layering possibility should be a deciding point, as you can do it with most soak off gels.
Sam Biddle did comparre a lot of these sytems and it may help you to read her. otherwise, go to some distributors and make a decision for yourself considering price, color range, client...
Gigi, I have to say it again, but I love you for saying this (and the rest in this thread)
I use tips cuz at times they can be time savers... they're my best friends, esp the new generation, white, matte, with a nice smile line.
I have seen MANY who would still do a French under a whole nail art'ed set... waste of time!
and if the chosen nail art can be done with polish then I just do my canvas a bit thicker and there you go, saves a lot of time and less dust, i can only agree!
I tend to have clients who will always have a Forever French... classic and nice.
for the others, I tend to "sculpt" a "canvas" with translucent pink and then do the nail art they want above, that I can easily remove.
so it doesn't take me more time, and nail art is charged...
