Hi Steve, sorry it's a bit off topic, what company did you use to book for Vannoya? None of the usual suspects seem to offer excursions there since DinTur stopped. We've been really keen to go for the top notch halibut fishing..
The sticky post at the top of this forum, Norway Generalised tips is best place to start.
250gm is fine for slow drifts/current, you may want something approaching double the weight if things are moving quickly, idea is to keep your line as close to vertical as possible. Giant Storm Shads and Savage Gear Cutbait Herring Shads are tried and tested (orange demon, puffin and mama rosa seem to be favourite colours)
Cheers
ST
