I love Portra, my 8x10 enlarger has a VC cold light so 8x10 for me would be contact prints under a 4x5 dichro source. Unique photo offers less than case quantities on Kodak Flexicolor C41. You do end up with enough bleach to last a long time. But for 150 bucks including UPS ground you can get enough to make over 10 L of developer, and bleach will last longer, fix is cheap ,I use Flexicolor final rinse off the Jobo.
Kodak C41 RA is the Bleach and Fixer chemicals to buy this shortens bleach from original C41.
