I have no idea what Twisted Weald trick y'all are talking about.
For my lockpickers I used my beetle to hold bags full of locked boxes. 20 boxes per bag (keyring limit) and I'd use 3 - 5 bags full. (I use UOAssist for the macro
UOAssist macros )
You record the macro with the boxes on you, then put them on the beetle and you can run the macro while riding the beetle. Works great.
