One of the suggestions would be instead of adding the fruit directly two secondary, I'd suggest you make a 'tea'. Depending on how much fruit you want to add / how fruity you want the final beer to taste, try using two pints of water, bring to a boil, then add your fruit for a min or so, then let it cool to the temp of your primary. Do not rush cooling, let it cool naturally, no ice baths, etc. Once it's reached your primary temp, run it through a clean paper coffee filter, so you don't get any seeds and what not into the juice. Then add the juice first to your secondary and then rack off your primary into your secondary.
For what it's worth. Hope this helps.
