I have a fair amount of a variety of guides but I need to buy some more for a spinning rod.
However as I am researching guides the specification information seems fairly lax.
Is there someone that has good specs on their website such as guide height and weight?

Yes there are height specs, no weight specs I remember. Component sponsors to the left.

I know anglers resource (Fuji) does for height idk about weight though.

most guides are just a few grains apart in weight the 2 foot ones are close the single foot are close this is the same for braced guided and naturally they will be a few grains heaver because of the brace unless your using titanium frames with ceramic rings there is a difference with just the wire rings they are some what lighter but not as durable or if they are the micro or mimina

it is a spinning rod for what type of fishing what is the line weight and taper of the blank ??

Think out side the box when all else fails !!!

All of the manufactures' catalogs have height data for all of their guides, but very few give weights.
Norm

Alps gives weight data.

All guides are said to be by their manufacturers to be about 30% lighter than something. :-)

It is interesting some sites have info and other don't have much.
Weight probably is secondary to other factors such as frame flex and height when matching it up to the rod.

I was checking out the Pac Bay catalog and I like their approach with the PDF which has a ton of info.
