If I am using whole fruit, I sanitize the whole fruit skin/peel on in star san for 5 min. Just did mangos that way. I have also used bagged frozen & thawed then pitched direct into secondary no sanitizer. Dried fruit, I always use a vodka soak. Now that I am writing this out it does seem odd to use different methods but its what's worked for me. Have you ever tried using orange marmalade or apricot preserves? You need to account for the extra sugar, but its a sterile way to add fruit flavors without a lot of fuss. (not my idea Randy Mosher, Radical Brewing).
