I have the odd dabble for jacks with a 6/7 weight 9-6 rod, and cheap WF7 floater and it is fine. There is an annoying trend in modern streamer fishing for both trout and pike always to to use gigantic lures . It seems to be a macho thing , judging by some of its practitioners but it isn't necessary at all for fun fishing. I first streamer fished 40 years ago when it wasn't a thing at all on rivers . I used lures typically 4s and 10s for chub , trout and pike , and I still do so. They work and you don't need a tough guy rod to cast them . And cheap decent capacity fly reel will do but do make sure you have a lot of backing for the unexpected encounters ...Ignore all the marketing flim flam about disc drag and spool made out of weapon grade unobtanium . A simple reel is fine , and may good ones are now made out of plastics now.
For traces I will again praise Surflon , the best knottable wire I've ever used , and by a huge margin .
To be frank , though , I far prefer piking with a light lure rod and 3.5 - 7g jigs on 2s- 2/0s . It's just as subtle and enjoyable as fly fishing but you can cast a lot further , and fish at different depths and speeds much more easily. I love it
