Velvia for flower, eye popping color
Sensia 100 with UV for Daylight, it has a built in warm tone, so it is not that blue.
Sensia 400 with FLD for indoor and night shots
I can't really tell the difference between Sensia and their pro counter parts. However, Sensia are cheaper and don't required professional storage. Velvia is still the best choice when I shoot flowers, althought it is a Pro flim I can't tell the quality difference between one that was exposed and developed immediately, and another that was left in the camera for two months before developing.
