I have been using letago casters for years. Very reliable and i like the position of the thumb when casting. I reckon i get extra 30 metres with thumb caster. My shock leader is 15kg .45 with .38 10kg mainline. With small single bait i get around 140m which drops my bait in deeper water and more consistent hookups. I did try braid but found it too sensitive when fishing in swells and breakout sinkers would keep pinging. I prefer a bit more stretch in the line.
