In reply to DonalO:
My guidebook (2009 edition) states:
Gyps Fulvus 6b+ (5c, 5a, 6b+, 5a)
Zimski cvijet 6a+ (5a, 5c, 6a+, 6a+, 4b, 6a, 5b)
It has been a few years since I climbed those routes but above grades feel about right, speaking from the memory.
BTW:
Water Song (6a+) is IMO by far the best route in that area (Veliki Cuk).
