We get way more mva's than fires out here, and I gotta be honest....the sawzall rocks all other methods. You get a dewalt w/an axe blade...you got yourself a cut windshield. Just keep the patient informed. On top of that, on a good pop, its a hassle switching tools all the time. you can go from removing a windshield to directly cutting pillars if you want to. zero time wasted. i mean..its called a sazALL for a reason..
you get a guy on the tools, a guy at the hydraulic pump, and a guy working the sawzall, and you'll have that thing filleted in no time..
