My only experience is with my two baby BPs, but they definitely have different strength levels.

My male who is about 3 months old and 100 grams doesn't have much strength and does almost no wrapping or gripping on me. This led me to dropping him a couple of times early on when he just slid right off my arm and one of those times him biting me for trying to catch him. I've since gotten much better at handling and making sure to keep him from a position that would let him fall. I feel too nervous to let him roam free as I'm worried he'll fall from a height. He doesn't seem unhealthy and does all his other business quite normally. I've watched him kill 4 rodents now quite efficiently (the last being his first crawler rat that he had to get two full coils around).

My new girl who is 2 months old and 91 grams seems like a muscle bound freak compared to my other BP. When she climbs on me she anchors herself with her tail and always give a good squeeze when there is any risk of falling. She did fall once when she scared herself with her own tail dropping down on the other side of my arm and her recoil sent her flying right off me. I have let her roam free in my bathroom and she went as high as she could before wedging herself into a the gap between my medicine cabinet and wall (and it took forever to get her to come out!). She is a great climber though and seems much more secure with stabilizing herself.

Maybe this is just baby stuff, but it's interesting the difference between the two of them.
