I would put myself in the 100M bracket, maybe a little over but when it comes to distance there are always better casters,there are a lot of variables, weight of line, type of reel, Rod etc. If you go to youtube you will see swing casters and even world championships, those guys can swing a piece of led around 300M, typically it is with very low weights, a pilchard weighs about 60 grams and a lot of the distant caserss all talk about a 40 - 60 gram weight... so after a "flick" or a "whip" like that what is left of the bait once it hits the water? a small sinker and a prawn maybe... but then how much effect the small sinker has in a ocean current remains the question but I suppose it would depend on what you are after.
check out this link for an idea on what I am talking about.
