Can someone explain reel sizes and how they affect fishing? I read posts that mention 1000 or 2000. What does this reference? Does one company relate to another? Previously I fished with 6-6.5 medium or medium light rods equipped with Pflueger President 30s and six pound line. Since starting crappie and brim fishing I have gone to 6-6.5 ultra lights with President 25s and 4 pound test, for no other reason than it felt better. How does the reel affect the experience and what do you recommend for casting jigs?
