While I understand that many toppers won't be suitable for use on a device like this, that doesn't make it an unsafe mod, any more than
any mech is unsafe in the hands of someone who hasn't taken time to learn about them. I currently already have a 4nine Prime for example. I rarely use it, but when I do I'm well aware of which attys I can safely put on top of it.
It's safe
for me to use because I took the time to study and learn about hybrid mechs. I would never on the other hand sell it or give it away to someone that didn't prove to me that they understand both mech safety and protruding center pins because I wouldn't be sure it was safe
for them to use. Safety is about the user's level of knowledge, not the device.
A chainsaw is unsafe in the hands of the wrong person, that doesn't mean we should stop everyone from using them...
