I don't personally use it, nor have I trained in it; so I can't base an opinion on true knowledge nor experience.
BUT I have read up on it quite a bit because I had dallied with the idea myself....watched some videos...
I had toyed with the idea because I wasn't ready to do L&P, and wanted something 'harder' and at the time, to compete (yes, not a good idea) with the NSS. (but then I changed uv gels and now don't have a problem with strength)
I personally don't see a use for it.
To me, in my inexperienced opinion, it makes far more sense to learn one system or the other (l&p or uv gel) or even both and go from there.
If you want the hardness of L&P, use it.
If you want the flexibility of gel, use that.
Mixing the two seems to be contrary in my mind, because you wouldn't get one nor the other.
Hard to explain what I mean... I guess what I'm saying is if you want the hardness, why go half way? If you want the flexibility; again, why go halfway.
I hope I made sense.
I'm not saying acrygel doesn't have it's place in the industry, for differences make the world go around, and having a variety is important.
This is just one system that doesn't make sense to me.
