Rate these FUJI guides please.

This maybe an over simplification, but here goes. The key words when
talking about guides is Porosity, Grain size & structure, and material
Hardness. They are all interrelated. The finer the grain, the denser the
material, the harder the material, the smoother it can be polished, the more
it eliminates porosity or pores in the material that can and will trap dirt.
Which then acts as sandpaper to wear at your fishing line, shorting its life
while increasing the line's premature failure (most likely under the stress
of a load, or that 5-pound bass that just snapped your line at the boat).
Also, the more porosity a material has, the more acceptable it is to stress
related failures such as cracking caused by the fine materials being
trapped, including sand, water, oil, solvents, etc., that will eat and work
at the material like a wedge.

We can talk about micron finishes, but I save you the boring crap for now.

They are probably American Tackle guides with a Zirconia (Alconite) ceramic
coated with Titanium Oxide to get the blue color, it should make the guides
very corrosion resistant, many people on the gulf use their Mag Bass rods on
reds and snook among other species.
If you give your rods a freshwater washdown when you come in I haven't had a
problem with the black Fujis, gold frames and than chrome frames seem to
corrode or lose their finish first.

You are right, but I don't always use my bass rods on bass, sometimes I use
them on the Gulf of Mexico, I use my smallmouth rod to cast to bonefish &
troll for big rainbows and brown trout that can reach 20 lbs, but more
likely will be 5 to say 12 lbs on light line. More accurately I use my
bonefish rod on smallmouth and finesse LM sometimes. Have also caught a
steelhead and Coho salmon on it from time to time and one 25 lb Chinook.
Was just trying to give you a visual reference to the different materials
and the reasons they may cost more.
Have a 30 lb rated boat rod with Fuji BHVLG Hardloy guides on it for about
20 years now, caught lots of fish on it in Florida when I lived there and
oversized 100 plus lb sturgeon on it now, they are just fine and I've had 80
lb Western Tuf-Line on the reel for maybe 12 of those years, with no ill
effects.
