I tried to use fishing line in my frames last year and the little Sh*ts bit them off, but yet they did draw comb with the line supporting it before they bit them off. So I am going to use stainless steel wire this year. Lets see them bite through that lol
Done similar this year too, I did contemplate fishing line but went with frame wire in the end. Pleasantly surprised at how easy they were to make up as well. I'm going to syringe a line of beeswax to the top bars this time round and see how they get on.
Like Tom I'm switching piecemeal. Worked out very well in the supers last year so I'll be alternating foundation with the wired frames in the new brood boxes to see how they get on.
