Generally to pick a binding, the following info is helpful:
1. skier type
2. height
3. weight
4. boot sole length
6. age
All that info is needed to figure out your din (binding release setting). Your din should fall somewhere in the middle of the din range of the binding. Knowing what type of skiing you're doing with it too is helpful.
The PL11 is super light and very durable but is recommended for lighter riders who are intermediate in their abilities. If you need a more freeride oriented binding, go with the Deadbolt 13 or 15.
