Ok, I can't seem to resolve this in my head clearly with the books, so I found this site, and it still isn't mentioned much in search

Wreck and Ram spells. They target by the ORT, and since they are combat spells you double the ORT for the object you are attacking. So with a Force 6 Wreck I could smack a hole into an ORT of 3 (pretty wimpy items) or just beat up something with ORT up to 6 I assume.
Now,
1.1)what use is the damage level of the spell?
1.2)Should you always sling a light?
1.3)Is there a definate advantage to a Deadly? In the Manipulation spells it talks about having them use secondary effects against the ORT and states that at Serious you are at a +2 and Moderate is a +4 to the target's ORT, with Light having no secondary effect. So would you run it the same for Wreck/Ram then, Deadly is even at the doubled ORT and Serious/Moderate are +2 and +4?
1.4)If so should light let you go with a +6 since there is no other effect to the spell?
Also,
2.1)what would the ORT of a gun be? If I had Wreck: Firearms Force 6, and I cast it at your gun,
2.2)what checks would we be facing then? I would cast the spell against your gun's ORT of ____, then resist my drain.
2.3)Now do you have to check against having the gun knocked out of your hand? If so, against what TNs/Conditions?
2.4)If the ORT of the gun is high enough that I cannot blow a 1 meter hole in it, then what does it mean to decrease the ORT of it by 1? Does the gun get mangled and have a chance to misfire?
2.5)Well, then at what point does the gun take so much damage that it cannot be fired anymore?
3) And on the knockback side of things, what if I had Wreck: Armor. Could I cast it on your armor only to make a hole, or can I also use it to knock you on your behind?
4) And final question I suppose: How specific should you properly get with wreck in these 2 cases? Is Firearm and armor good enough, or should it be Pistols, SMGs, Heavy Gunnery categories, and also light, medium and military grade on armor?
