He's not alone. When I got more heavily into DIY, I expected most of the experienced DIYers to be using complicated coils. To my surprise, the majority use single simple round wire coils at low wattages. I thought I vaped low at 30W. Some of the folks in Discord barely hit 20. And these aren't n00bz with unsophisticated palates, they are highly regarded flavour reviewers and recipe developers.
That said, it's not unanimous either that single, low and simple is the way to go. Some, like ID10-T, use dual Claptons at (for me) relatively high wattages of 45-60. ConcreteRiver runs simple coils but goes dual at 60W usually. So there's a spread where everybody finds their happy place. But the assumption that fancier coils deliver better or richer or more saturated flavour doesn't always hold good.
I also heard an interesting theory that reverting to single simple coils and low wattages will help to overcome vaper's tongue. It makes sense to me as I think vaper's tongue comes from olfactory overload. If you're chucking enormous clouds at 140W from your sick quad stapled staggered framed fused Mohican Juggernauts at 0.08Ω and draining a tank in a dozen hits, you are inhaling more volatiles and flavouring molecules per puff. So you overload your senses faster and eventually they shut down. Again, it might be intuitive to conclude that inhaling more flavour molecules in a puff is going to give you more flavour. But that's like assuming that 12% Strawberry Ripe will give you twice as much flavour as 6%. Often, less is more. I prefer to be searching a bit for flavour than bombarded by it.
