That is truly a very fortunate position to be in. The more tackle I buy the more I am drawn to the esoteric side. There is just something really great about going to the river, beach, or lake with a quality piece of tackle.
Anyone can run to the store and buy the latest thing. but not everyone can show up on the river with the likes of say . . . a Robert Meiser custom rod and perhaps a Maurice Noel reel. [not that I do] That is an extreme example but that idea can extend even to just the fly being fished.
Let us know what you end up with, and enjoy the process!
