How small & light would you like to go? From left to right:
3-weight reel on a 7ft-8" (To give you a relative idea of sizes involved, this being the large reel, the spool is only 2-5/8" outside diameter
2-weight on a 7ft
1-weight on a 6ft-7"
0-weight on a 5ft-5" And yes, even the teeny-tiny toy will cast 30+ feet with little effort.
But honestly, this is what's called having too much time on your hands when you're too far from the fishing
