There's lots of detail, also, about guide size and spacing on both spinning rods and baitcasters. Maybe more than you want to know. There are plenty of people who don't care about this sort of thing. As in "Here's my money. Just gimme a rod." But there are plenty of others (like me) who obsess over the smallest details. For those, the Anglers Resource sections on static loading and guide spacing are truly enlightening.
