I agree with Kernel. Get the Wolff springs and you'll be happy.
If you want a 1st class trigger job, consider Teddy Jacobsen at Actions by "T". (www.actionsbyt.com) He'll use the Wolff springs too, but he'll also polish every piece inside that trigger that needs it, and it will be soooo smooth! It'll run about $120 or so, but well worth it! (he'll also clean it, lube it paint your sights if you want and other stuff free of charge)
