p.1 #17 · Cotton Carrier Side Holster vs. Spider Holster | |
Ok so I have looked into both the CC and the Spider myself in the brief time that I wanted to have something to use for my second camera body to hang off either a belt or some other type of "sling" design and here is what in the end makes me lean towards the Spider.
The CC uses two materials that I don't like being used to rely upon when a $3000+ camera and a $1000-3000+ lens is being mounted to it.
"Plastic and Aluminum".
I understand the plastic part is aircraft quality but the fact of it is it's still plastic. Even if you were to use Carbon Fiber instead for the same application it would still be exactly the same.
Several things I learned when I was a machinist and welder and all around thrasher of bikes when I worked in the cycling industry.
You never try to use Aluminum, Carbon Fiber, or any type of plastic in a load bearing application. If you do have to use it, you either gusset the hell out of it (welded), make the piece larger (Cast) or you have to build up the joint with layer after layer after layer (Carbon Fiber).
The reason is that you have what is called a "Catastrophic failure" issue. Aluminum, plastic, and carbon fiber doesn't ever give you an indication of when it's going to break before it does.
It goes straight from "hmmm, looks fine" to "Whammo, broken".
Steel (Stainless, Chromoly, etc...) at least 90-95% of the time is going to give you some type of a crack before it fails. And you can still even use it in most applications. The other 5% is because the load was so great in the first place which is why it failed.
Ever wonder why when you get a cara-beener from a tourist place and it's aluminum, it always says "not load bearing" on the side? And why all professional climbing cara-beeners are steel? Even better find out what percentage of roll cages on NASCAR cars are Aluminum.
Aluminum is a great material for various applications, just not many that are load bearing will you see anything but either steel or even titanium.
My other favorite metal, besides Megadeth!

Honestly I would rather that Spider use an all Stainless steel setup because of this reason, and who knows maybe over time they will. Or even better use a Titanium mounting plate because of weight and strength. But in the end it comes down to a cost factor.
I am going to try the Spider design because it just looks sturdier than the other. And I want to use a 1D MK III and 300mm f/2.8 non IS lens on it.
That's my 2 cents worthless...
