Have the chance to shoot my first nhra national event with media credentials at the upcoming maple grove race for Friday and Saturday qualifying and wondering if you guys think I should just use my current gear or if I should rent a 300L II or a 200L F2. Reading the rules the nhra doesn't allow flash so I was leaning towards the faster 200L for night photos and because the nhra restricts how far down track I can go and I don't want to risk running into the issue of the 300L cropping things to tight. Would trying to hand hold either of those for 10-12 hours be a bad idea? (I'd imagine I'd only take said rented lens and my 16-35 and a 1.4x TC with me)
