A few questions about Busch Gardens Africa?

Ok, I live an hour away from busch gardens and i've been their sevral times. I like rollercoasters somewhat. It takes my a long time to build up courage to go on them. The only coaster i've been on i Bucsh Gardens is cheetah chase. I'm going on a feild trip their next week and I'm thinking about scorpion and mabey montu. How scary are they? I here scorpion isn't very scary but its rough. And I hate drops, but loops are okey so montu wouldn't seem so bad but I don't want anything to intense. Oh, and how bad is gwazi? I mean for someone who doesnt like drops. Oh, and I have this little fear of coasters crashing by the way lol. Are they safe? Thanks :)
