I selected Bamboo, used my Schliske 3wt the bulk of last season and that'll be the story from now on but still own and use a 4wt TXL when I need to travel with a smaller tube or just when the fancy takes me. Used the TXL or similar up until last season.
Bigger rivers and the very occasional foray on stillwaters or when fishing for Pike I use Graphite.
Salt, I don't do, maybe this coming year I will. If and when it'll be graphite.

Don't own anything other than fly rods, not a judgement just a personal choice for fun reasons.
