I collected a root-type piece of wood the other day, but it has little pointy nodules along some areas of it. How big a danger is this of tearing skin on the frogs, etc? Or do you think they will be affected by it much?
Better safe than sorry is a good thing to go by, but a lot of broms are spinny so its a matter of the ammount of weight put on them. I know my imitators never seem to have a issue climbing over a spinny brom.
