copper can be effective can also ( mostly ) be a pain in the ass
no your reel isnt big enough
yes you can run it down the shute...yes it will tangle
i suggest if your gonna try it get a Z-line or a new church board big enough to handle it and pull it off that to get it out away from your spread
there is days our copper rods are the only ones to take fish...also days it never fires
i run 500 / 400 /300 /200..... if i was gonna run just one it would be the 400....gets ya somewhere between 85-95 depending on what your pulling/speed/currents
good luck
