Just to say I fish a lot for black bass in Spain and for 95% of the time I use poppers. Also 95% of the takes are within 1 metre of the shore.
Only time I use 'flies' is when there has been a lot of rain (like now!) or snow melt as the bass are then very deep but even then some will come up.
I cast the popper as near the bank as possible, (often onto the bank) and
then do one hard strip (you can hear the pop) and wait for around 15 seconds and then strip in slowly.
Takes vary from a 'slam' to a gentle sipping that you can hardly see. Popper seems to sink. Once I even had a bass take before the popper had landed!
Other point is to keep rod pointing at the popper with the line straight. I then strip strike as I lift the rod. Any loose line you are unlikely to get a firm hook hold.
Enjoy!
