I use mainly Fuji Superia from 100 -400, 95% of the time and occasionally Fuji 1600. I have used Agfa Vista once before it disappeared - liked it - and have got Kodak VR 400 in the camera now to try. My one disappointment was Konica but that may have been my processing and printing. It just didn't have the vibrancy of Fuji or the subtlety of the Agfa.
Currently my split between B&W and colour is about 70-30. I still find B&W quicker to do(easier and quicker set-up time), and I am less anxious about it
All are 35mm.
