I bought a 'windprotractor' once , thought it was a good idea but never used it , stayed with the CRP5 . As for en route nav there are many variations of the 1 in 60 rule which make life so much easier in the air than mucking about with protractors and such crap in the cockpit . Personally I make my track my heading and allow 5 degrees for wind if that isn't enough allow 10 degrees and just bracket from there . You should seldom need much more than 10 degrees unless the wind is really blowing a gale . It's surprising how accurate a good guestimate can be .
