You might want to join and look at the spreadsheets and network diagrams at http://tech.groups.yahoo.com/group/RL21Project/
to see where you fit in best.
If this is you,
f31126 Olazabal R-L21** Spain, Andalucía, Cadiz
Then the two guys you are closed to that are also L21+ confirmed and 67 markers are:
f71421 Carrucan R-L21** Ireland, Munster, Co. Clare
f6475 Longacre(Göteborg) R-L21* Sweden, Västergötland län, Göteborg
The GD's are 11 over 67 which may indicate a MRCA about 1500 years ago... so not recent by any means.
