Correct. I believe you'll be limited on a BTA option if just using the ultimate scoops. You could Macgyver it and wrap velcro straps or long zip ties (velcro would prob hold better due to the shape) under the padding which would go around the scoops as a possible workaround. Not sure how secure the BTA would be though... There are also numerous bolt inserts under the scoops to adjust reach that may be utilized if you find a bta bracket that could reach those inserts.
