I have 3 Rolands,
I use Flexi 8.62, have used it since 7.6.
Works great, does the best job of putting a contour cut onto a file.
Yes, I had it profiled, every major upgrade.
I also use Onyx 7.3, had it profiled as well. I use that for straight printing.
I also use Wasatch for screen separations with the Epson.
Only thing I use Versaworks for is to check the ink levels on 1 machine I have not already converted to Bulk ink.
I have not had any real issues with any RIP that I couldn't solve with a little reading or asking here.
