Hey guys, looking for some advice hoping to avoid an expensive trial and error. I usually fish stake beds and brush in 4-6 FOW by sitting back and casting a bobber. I am wanting to try using a long rod and sort of jigging the brush instead of casting into it. i have 12' rods i use spider rigging, will these be good enough, or should i invest in some 16' rods for this type fishing? Also what is your preferred rod for this style of fishing?

thanks alot!
