If your rest is a fall away rest then chocolate chip cookie vane out would give you the best clearance (provided the fall away is timed correctly). If the rest is a prong style (I can't tell by the photo), chocolate chip cookie vane down would work better. If it is a solid launcher (as it appears to me), just play with the vane position, between up and to the left, until you can get clearance.
Or get a whisker biscuit and shoot chocolate chip cookie vane out. Or a rest with a side plate or berger button, and shoot chocolate chip cookie vane out.
A flatter cable slide may help. But you will need to try it first to know.
