The veteran Redmond has been among the most prolific batsmen in domestic cricket for over a year but has been unwanted in his bid for a test recall so far; Raval is in strong form for Auckland and well regarded.
Openers Hamish Rutherford, in particular, and Peter Fulton, Dean Brownlie and captain Brendon McCullum should all relish getting a look at the West Indies attack.
Tom Latham - on the fringe of getting a test chance, remembering regular No 3 Kane Williamson is almost certainly out of the first test - is another with much to play for.
Fast-medium pair Sheldon Cottrell and Shannon Gabriel are vying for first test selection, while offspinner Shane Shillingford - assuming he passes an ICC test on his bowling action - could be the biggest handful for New Zealand.
Otago allrounder Sam Wells, Wellington seamer Illy Tugaga and young Auckland A batsman Robert O'Donnell - son of coach Mark O'Donnell and a centurymaker for Takapuna in club cricket last weekend - round out the ring-ins.
Now a hamstring tear has counted Chris Gayle out of the tests, the West Indies will lean heavily on the rounded 39-year-old shoulders of Shivnarine Chanderpaul, on his fifth tour of New Zealand.
The little Guyanese, the possessor of cricket's ugliest stance, has a test average of 51 from 150 internationals as proof of his qualities. Barbadian Kirk Edwards, with a test average of 39 but having played the last of his nine tests 18 months ago, is the only other specialist batsman at Lincoln. To him comes a chance to put his nose in front of his top order rivals for a test spot in Dunedin next week.
