Bruce I have been using the Pink 15kg Platypus low stretch mono for trolling (and everything else for that matter)on a TLD20. Dont know about its high visibility but it does seem to be able to knock over anything I have encountered. As far as rods go I am using an 8-15kg live fibre. This seems to do the trick alright as well. I dont reckon you need that heavy a kit for trolling for your normal type pelagics but thats just me.
