Composite shingles

  Hello, my name is Curtis, I am a experienced contractor, however am still fairly new to the industry (6-7 years). I have been wanting to get some more synthetic slate roofs on the go. I am just wondering if anyone reccomends any brands and the material price generally for a small contractor such as myself. I normally use euroshield and get it for about $5/sqft overall material wise all in, however am looking to try out a new one like davinci or certainteed, and want to hear something from someone in the industry thats not a supplier.
