Technique is everything, but it seems that 'The Korda Boyz' pushed heavier test curve rods as the long casting answer over practice.
I'd frequently get back from fishing Sunday lunchtime and then spend the afternoon casting over the field.
If we go back to the 1990's I was casting over 100metres with 2Ā¼lb test curve rods and original 4000 size Baitrunners, 2Ā½oz leads, shockleader and 8lb mono. The 2Ā¾lb Armalite mk.ll update saw 10lb line being used with leaders, to 2.75lb SP's and 15lb line and 3oz leads and reaching over 125metres, using bags and stringers.

The Korda Boyz, a tongue in cheek remark about tackle brand sponsorship pushing heavier rods because they simply couldn't reach the distance because technique is lacking. Easier to buy new gear over spending time practicing.
