Upstream dry fly only, that is the rule stablished in some English chalkstreams by their managers. The rule in the Balkan spring creeks is exactly the opposite: downstream dry fly only, this time imposed by the fish themselves; the only law that incorporates in itself the punishment of frustation of those who violate it.
Nothing like a downstream presentation to deal with a maze of uncountable conflicting currents for a long drag-free drift. Reach casts, pull-back mends and parachute casts, alone or combined, are their ingredients. Still learning how to master it, but isn’t that never-ending learning process the greatness of fly fishing?
