Main problem with new spokes is clearance,viz;spokes with head on outside must not touch brake drum when bolts are tightened (H19).If using standard across 4 lacing pattern some heavier guage spokes just touch the head of the spoke on the next slot.This can cause dangerous local stress, particularly in a rear wheel.The head of the contacted spoke may be lightly relieved to avoid this.Some manufacturers give the spokes too broad a sweep coming out of the flange which gives rise to these problems.Do a trial lacing and check for all these problems.You may need to "fettle"the bend on either the inner or outer spokes to get them sitting right.I would use the clearance slot for the head and see how everything sits.Cheers, F5AB/2A/7945
