I love the Swedish and have caught Perch, Lake Trout, Smelt and other panfish on them.
I am not sure the size number, they arent huge and load up 4lb line well.
I like the plain silver with red flapper and treble, then I change it up to suit the conditions if there is no bite.
I usually tip with a spike, then if no action add one at a time until there are three.
If there is no action then I will tip with a waxy.
If still not action, use an eye if I have one.
Failing that....try something else.
