Graham,
The problem that Billy Lane had, at the time when he was fishing, was that his choices of rods were very limited.
I often wonder how some of the 'greats' Lane, Dean, Ashurst Snr. et al, might go about their 'trade' with today's modern equipment?
It is alot easier to trot at 20 feet from the bank, directly off of the end of the rod, with a longer rod, believe me. Yes, they are heavier than a 13 feet model, but then that is a given disadvantage.
I used the Bolo' rods extensively on the deep rivers in Norway and Sweden; where the fish were not interested in a static bait, which was more often than not, otherwise I'd have been on the lead or the feeder.
