Ok, I know, it's been done and there are several threads/articles out there, etc. However, I decided to give this a go and found the details of other ventures to be slightly lacking when faced with so many decisions. So I thought I'd post a thorough list of what I found to be helpful details.
I, like many, went the golf club shaft route. You could hunt down goodwill clubs (good luck finding a matching pair), hang around golf ranges waiting for people to break stuff, call local golf shops, etc. for freebie scrap shafts, but there are two problems I found with this route.
1) the shaft you are using to support some of your weight has already suffered one failure and may not be far from another.
2) many golf shops can't/won't sell used shafts due to liability reasons.
For this reason, I found it acceptable to drop 10 bucks a piece on new shafts. You can sometimes find deals on ebay for closer to 5 bucks a shaft. However, shipping may get you in the end. I ended up buying online at golfsmith because I could have it shipped to a nearby store for free.
One benefit of buying a golf club shaft is that all the weights and lengths are listed online. However, there IS ONE IMPORTANT THING THAT MUST BE MENTIONED HERE:
When buying shafts, look for a tip size of .370 as this is a perfect fit for Leki tips. You can install the tips per Leki's instructions by simply slipping them on and banging them onto a hard surface. No glue required. The .370 size is actually not very common. I took a Leki tip to a golf store and slid it over the more common, smaller tip and it was a much sloppier fit. So tip size is important.
I had a hard time finding a sporting goods store that stocked cork grips for fishing poles. Had I lived closer to a Cabela's, this would not have been a problem.
Though I did notice while shopping for golf club shafts that they had a wide selection of grips available, most of which also have weights listed online in grams.
They are considerably heavier than cork, and should I hit up a cabela's soon, I may very well replace the rubber grips I ended up with.
But despite the weight penalty, there are advantages to using golf club grips:
1) You can cut to fit or leave the full length of the grip if you want to use the poles on extra steep ascents (these are fixed length, remember).
2) No glue required and you know the grip is going to fit. This also means they are easily replaceable.
3) Before you install the grip, you can use the hole in the top to install "straps" as seen in the photos. Just make a loop with a knot at one end, push a piece of coat hanger through the top of the grip, attach the loop to the end of the coat hanger (make a tight J hook with a set of pliers) and pull it through the top, letting the knot stop the string inside the grip.
So the shafts were roughly 10 bucks a piece, Leki tips are 10-14 or so a pair depending on where you get them. and then the baskets for a couple of bucks a piece. The grips in question were 3 bucks each and the cord for the straps I already had. So all in all, about 20 bucks a pole, 40 a set.
The short ones for the wife ended up weighing right at 5 oz. each and the longer ones came out at 4.8 oz. each.
