raking is designed to open a lock in minimum time... loads of info about this already... MIT guide talks about it as well...
most of the picks in the 'super sets' will never get used... i reckon you could sand, or file the picks down to slimlines...
if you told us where you lived it would be easier... the UK and europe use small keyways in there locks so slimlines are needed, american locks are bigger and so normal picks work. pictures as well would help
do a search for "training lock"... been discussed loads... Era is good if you live in the UK
