So I have a set of the old style camalots that are still in great shape, but I am considering buying a new set of C4's for the weight savings in the pack. I was wondering if anyone knows where I can find the specs for the old camalots so that I can do some quick math to see if I think that it is worth the money to buy a third set of cams.
I have tried Google, and the search function here, but I think my search skills are lacking.

This may shed a little light on what you're looking for.

I've heard anywhere from 20% to 30% weight reduction vs the previous generation.

That is very helpful, thanks muttonface.
So here is the math from the article.
0.4-3 saves 5.1oz.
4 saves 1.2oz (vs old 4)
5 saves 2.1oz (vs old 4.5)
6 adds 0.5oz. (vs old 5)
edit 7.9oz saving so far, but there is no 3.5 which saves 10oz.
So overall 17.9 savings (over 1 lb).
Overall C4's from 0.4 - 6 weigh 71oz (4.4lbs)
Overall old set from 0.4 - 6 weigh 88.9oz (5.6lbs)

Not bad.

So I was thinking about swapping carabiners also.
10 neutrinos for racking cams at 1.3oz (36g) = 13oz.
Add 20 for 10 slings = 26oz.
So 39oz total

30 camp nanos at 0.8oz each is 24 oz.
So nanos save 15 oz (0.9lb).
2.1 pound savings total between new cams and new biners.
I'm sold.

My rack is about 8-10 years old, and OMG, what a weight difference there is compared to the newer generation gear. My rack, compared to my boyfriend's newer generation rack (with about the same amt. of gear ) seems twice as heavy. I should weigh our racks, and compare for fun.

Nah, BD is coming out with micro-cams this summer, but I wouldnt expect C4s to be replaced anytime soon.

This chart answers your question and has a bunch of helpful numbers:

Sheesh are all you folk really that close to "the edge"? I mean if I have a healthy "morning constitutional" and ease up on the breakfast coffee I can hit or miss five pounds from one day to the next. I thought part of the lure of trad climbing was not worrying about weight. Where's my ham sammich and Pabst?

click on the compare tab under the picture. It has the size and weight differences of all their old vs new cams.

Or just look at this picture I got from the same place.

stick with the old cams, it's like saying 1 pound is work a few hundred bucks.

IMHO the old camalots had better sizing, the 3.5 and 4 fit better than the new 4. But thats just my opinion.

i've heard pube-shaving is an excellent means of cutting weight.

I definitely appreciate the weight savings when climbing harder routes. A pound difference hanging off of your waist makes a noticeable difference! Especially when you are climbing multi-pitch. I like the thumb loop design better too; makes placing a bit easier when in a crunch. I bought my C4's used on the for sale forum. You can piece meal a full set together if you are patient.

My trad rack now weighs about 6.5 pounds, down from 8.5 pounds. I am using a full set of metolius master cams and 0.5 - 3 on black diamond. My weight savings was biggest in switching to Mammut Moses wire gates (from BD neutrinos) and ultralight curved nuts from Metolius (from BD nuts). If you replace 50 carabiners on your rack (consider your racking biners plus your alpine sling biners) you will save a pound of weight with the Moses carabiners over the neutrinos. The Moses biners are pricey though. Using the master cams will give you two extra cams for the same weight as a set of black diamonds. Two extra cams is a great help on longer routes. The ultralight nut set from Metolius will save you 1/3 of a pound over the black diamond nuts. I sold my black diamond nuts on the used gear forum for $45, bought the ultralight nuts on sale for $109, so it wasn't that bad out of pocket.

The noticeable difference from a lighter trad rack is where the weight is positioned. If your body weighs more, you don't notice it since it is distributed well over your whole body. Weight hanging off of your waist or a gear sling hangs in a concentrated load which is definitely noticeable. The alternative option: get stronger and don't worry about it.

Alright if we are measuring feces you have to use the correct measurement..... I believe its called a Courick- and it weighs about 2.5#s/ katie courick.

This might help . . . no need for math and it is from BD.
