Won't be trying them on running water Mike. Tomorrow is a still water day, hopefully the resident fish approve.
hi Liam,
for sure, there are no rules (yaya !
) and you just might get some interest on still waters with the ceramics
however, they where designed for rivers and maybe specifically for faster waters or for 'induced take' presentations on slower flows.
basically, they're attractors with minimalist features yet strong triggers, at least as far as the main body of the bug is concerned.
in other words, for waters where fish don't get a lot of time to inspect the imitation and just gulp down whatever might look like food.
older in design as the spannish Perdigonne style of nymphs, both styles predominantly feature a very smooth, hydrodynamic shape which makes them sink very, very quickly without having to weigh a ton to get there.
be sure to let us know how you get along with them
ps- watch your drifts or you'll lose them all on the bottom
cheers,
marc
