I bought some of those rapala knock offs from lureking on trademe about 6 months ago, i got 14 for bugger all they looked really good but wouldn’t swim very well. After a while i realised that they are not weighted ( they have no keel) they would wiggle fine about 12 times then turn over completely losing their action, any trout following must think wtf??!!
They are also plastic and hollow while rapala’s are made of balsa. Not all is lost though using a soldering iron i burned a hole between the 1st hook and the bib and inserted 3 split shot then glued over the hole now i have working lures still at a fraction the price of rapalas.
Keep this in mind if you are goin to get some chinese knock offs. I probably won’t do it again.
