Best Jool orbit to stay away from the moons?

[CobraA1]

Trying (rather unsuccessfully) to get a mission to Pol, and a couple of times the time warp has simply killed a maneuver node far into the future (about a year or so). Often, it leads me on an escape trajectory from Jool. I suspect that I'm being flung by a moon or something. Is there a good way to avoid this?

Check the size of each moon's SOI (select it in map view, and try the Info icons on the side: one of them has technical data). Simple arithmetic will tell you which altitudes around Jool ought to be safe.

Caveat: on higher timewarp, the game likes to create encounters even if they're technically not possible. It's as if SOIs get larger during warp. Such phantom encounters are much more likely if you do not watch the vessel. Workarounds:

1. leave a generous safety margin if possible,
2. don't warp too fast,
3. stay focused on the vessel you care about (having it selected in the tracking station will do).

You mean straight from Kerbin to Pol?  You can always set your initial Jool flyby periapsis so it's tangent to Pol's orbit, using some combination of prograde/retrograde and radial in/out.  Then capture burn once you hit the tangent point.  If you're never closer to Jool than Pol's orbit, the meanie moons will be powerless to stop you.  But you will lose out on the most efficient ways to capture into the Jool system (aerobrake if you have a heat shield, gravity assist around the big moons, or just use the Oberth of Jool or one of its big moons for the capture burn).  

My usual MO is to do the Tylo gravity assist to capture around Jool, in which case obviously you WANT an encounter with Tylo.  It's relatively easy to avoid unwanted additional encounters doing this - you're definitely not going to hit Bop by accident unless something has gone very, very wrong.

Thanks. Finally made a successful mission - hours later, sigh. I definitely need to use a checklist for these things, keep forgetting things, making mistakes.
