Most of all, Tricams are just fun to place due to three things:
- it can be hard to find a good placement
- sometimes they work when it seems nothing else will
- their is something cool about their simplicity (like a hex)
In pocketed areas, they can sometimes be the most bomber piece. They are durable and relatively cheap compared to a cam.
Dislikes
You really have to be careful about tricams walking. Sling them well and then still be careful about them moving about. In addition, they can be tricky to clean, especially when they are placed in a bomber and tight placement. Considering their relatively infrequent use in Yosemite, I am always surprised how many fixed ones I see on big walls. That could be because many people use a hammer with them: a big no no.
Best Application
Tricams are ideal in pocketed areas or areas with horizontals. Gunks climbers swear by them.
Value
When compared to a cam, they are a pretty good deal. However, when thought of as a specialty piece that will not be used much compared to a cam, they are a bit of an extra.
