When I was young and naive in the specimen sport I read all the UK mags and fished funky rigs and only Mainline boilies. I was so obsessed with "quality" bait, if I didn't have Mainline I didn't fish, full stop.
A couple of years of the most invisible kind of success down the line I met an angler on the bank who out fished me so comprehensively I had to find out what secret new Mainline HNV-maximum-attraction-big-fish-only-your-salary-for-1-kg bait he was using. Clearly this guy was a Mainline bait tester with a science lab and a team of engineers to build state of the art balanced and weightless camo curved combi rigs that selectively hook big fish from 3 feet away. Like real specimen anglers.
I was so convinced of his pedigree even his bright yellow t-shirt suddenly seemed better camouflaged than my own khakis.
I went over for a chat, we became good friends and fishing buddies and it turned out his secrets were simple: good watercraft, simple, effective rigs, an effective feeding campaign, putting in decent quantities of bait. The end.
It happened that he was using GT, he'd tested various brands and found GT to be good value for money, decent quality bait. I had no grounds to argue and adjusted my approach to match his. I never looked back.
It was a lesson in keeping it simple and focussing on what works, not what sells.
