I only fish two myself, my club waters are two rod rule and when I go to day ticket waters I only fish with two even if I can use more. 👍
I did buy a 3 rod rod license but never used the 3 yet, I think I'll go back to my 2 rod licence this year.
But everyone to their own I suppose it's what you get used to, I've always fished two on the odd occasion that have used three in the past I've bought the extra day rod licence. 👍
