I’ve built a hand full of bfs rods and really got into it. Like some have said it’s not cheap to buy the real bfs reels from japan. Ive got 3 of the 2016 aldebaran bfs that are 300$ but with the right rod you can cast some stupid light jigs. I’ve been playing with some of the aliexpess bfs reels and for trying out bfs gear they get the job done. They won’t cast the 1/32 - 1/16oz jigs like the aldebaran bfs with no effort but most will cast a 1/16oz crappie jig and they are mostly around 60$ a real. The key to it is having a rod that will effectively load the jigs up to cast them. Look up “the reel test” on YouTube and he has gone over most of the reels you can probably buy. As to line I use 2 or 4 pound mono.
