I'm gonna show my ignorance here, but what makes a parabolic action what it is, and what are the other actions one would find today?
I'll take parabolic to task. The classic para taper in glass is 6'3" Berkley Gowdy Para/metric, and in cane, 7'4" PHY Driggs River.
The tip is relatively fast, the mid sllghtly slower, and the small-diameter butt feels soft, loading deep into the handle.
They respond very well to short, smooth arm movements and haul, launching surprising line length.
The taper is easy to achieve in short rods, and they tend to be very good tools for fishing overhang with big flies.
Though they don't call them para, two examples of para taper in modern graphite rods are Sage RPLX and TCR - unforgiving, but rewarding good casting habits with extra distance (I consistently cast my RPLX7 140' one day when fishing the surf).
I have the Izch PBEX8667 para S-glass salt rod. I have shot the rod before and stood in amazement looking at it, wondering when the shooting line was ever going to stop.
As others stated, progressive is more typical in glass, and e-glass is perfect for super-progressive (the old Heddon Trout tapers, and the cane example is Thomas Light Special). Progressive tapers typically give you better control with short line lengths, effortless long casts when you load deeper into the mid, and a big-fish-fighting butt.
Super-progressive are the ultimate dry-fly tapers, with a tip that lets you accurately cast the leader alone, and faster mid for quick casts.
Progressive tapers work better in longer rods, the exception being Phillipson's short rods (among the few short progressive tapers that roll-cast well).
Para taper is always the best choice for shooting line. Progressive taper is always the best choice for accurate casting.
Most newer rods have gone away from either extreme, and are closer to classic wet fly tapers/ semi-para.
Wet fly tapers (semi-para) are something in-between. In longer, slower rods, these can be really deep-flexing and noodle-y.
We call them semi-para when they're fast rods, and wet fly when they're slower.
but the taper tends to be smooth flexing from end to end, good with big flies, all-around work horse rods, and my favorite example is cane, 8' Heddon 1-3/4f. I do have a glass example, System 5 - neither of these rods have a noodle-y bone in them, and plenty of power.
