Hi Bob.
I flew in and out of Vagar VFR quite a few times some years ago. Wick is a good place to set off, and the distance is about the same. Andrew Bruce, at Wick, has a lot of experience assisting Atlantic crossers.
The weather at Vagar is very unpredictable, with fog suddenly drifting in off the sea, so make sure you check the latest before you pass your PNR.
JW 411 is right about the winds. If the wind is in certain directions above certain speeds, it can be VERY turbulent. The terrain is also VERY unforgiving. I learned to trust the ATC guys. They have a lot of experience predicting the local wind effects. If they say don't come today, just don't go!
On the plus side, the people are friendly, and on a nice day, the scenery is spectacular with jagged mountains rising almost vertically from the sea to >3,000 feet!
If you get the chance, fly the 'Waterfall' approach to Rwy 30!

Ps. The water is very cold up there, even in the summer. I would consider immersion suits, with some warm layers underneath essential in a single.
