it depends entirely what you breed him to. since crele is essentially barred on wild type, getting the barring would be easy, getting the wild type markings harder.
none of the other orp varieties use the wild type (e+) variety, so it just depends. breeding to black would be probably the easiest, since E is dominant and very obvious (and easier to get very good typed birds) but black is also capable of hiding other mutations too, that may affect the presentation of some mutations. (mahogany, black tail, Columbian, etc)
theoretically, presuming the black doesn't carry anything contrary to what you're looking for, first generation would be all black, some barred. keep them. breed them back to each other, you should get a few wild type from the mix, some barred, some not. keep the barred to use. breed back to black and the original sire, mixing up the genetics as much as possible with blacks to prevent serious inbreeding, always keeping birds at least split to e+ (visibly black but one parent was e+) that do have barring.
ok heck with it. I just talked myself into it. i'll take him. LOL
