I completely understand, that makes a lot of sense to me, thank you very much!!
On a completely different note, do you know how strong does a joist need to be to hold up at X-Pole on a normal ceiling? Do you need to test the joist at all or the fact that you found it with a stud finder mean that it would be strong enough to hold? (This is for going inside a house – not on an exposed beam – using the dome mount!)
