mouse flight is more responsive than keyboard...and if you accidentally bump a ring, the auto-level with keyboard could present some serious problems getting back on course(since you must map the disabling command yourself).
Just keep your cool, you are allowed a re-try, and a bump or two won't hurt you anyway; Hovis stops momentarily to turn on his defenses and gives you a huge gap to pass him in.
Freighters are also not the best ships for this. There's a very good reason why the Hood offers that light fighter.
Reaper: $200,000,000.
Rockets: $100,000
The look on that pilot's face when you launch a full pod of screamers up his tailpipe: priceless
