You can probably get Pro-Piks from Dave Bresnan at Frets Unlimited, in Fazakerly, Liverpool, or maybe from Andy Perkins' shop in Kent
His Website.
I've used silk gel nails from a nail salon for clawhammer banjo. My verdict is that they're totally perfect and are still great even when your nail's grown for three weeks, because there's a good seal between the fake nails and your own. They don't fly off and land in someone's beer like the stick-on ones do.
Cheers
