Score and snap works good for straight lines, for wheel arches I use curved lexan scissors, cut close to the line the clean it up with a sanding drum on my dremel tool.
Not much of a score-n-snap kinda guy myself. I just use my curved lexan scissors for everything. I do agree with Nessel. The #16 blades are awesome for these jobs. Especially when cutting your mask details. Unfortunately they're harder to find than #11 blades.

You asked about nice and straight. That's the score and snap. For all the rest, same as NCNitro does. Curved Lexan scissors and a sanding drum in the Dremel.
For the body post holes, a conical stone in the dremel.
Exactly. That allows me to mark and line up the posts in the perfect spot, every time.
NCNitro talked me into the score and snap a while back, and now I wouldn't do it any other way on a straight cut. Try it once and you'll stay with it. It's absolutely accurate, it's quick and it's clean.
The last lid I cut out was the large Helios body, and there's not a curved cut on it. It was all score and snap. Had it cut and ready in 15 minutes.
Mine is waiting to be painted, but that large Savage version is going to be a scale lid on the crawler.
