Hey MJF,
As with most of the rapalas, these are a good lure. I havn't used that size but have done Ok with the 140mm version one on snapper while trolling for early season pelagics in my Kayak. I paid $24 for the bigger version. I reckon they would be great for JEW - albeit a bit expensive if your are around the rocks. The action is fantasic and the finish on them is very good. Good luck and let us know how you go.
Cheers
FP
