The only time I've had any problems with anything catching the brakes was shoelaces or pant leg snagging on the post on the pads. I switched to female bolt pads and haven't had a problem since. Fly, eclat and odyssey make female bolt pads, I do believe sprinfields come with female ghost pads so you should be golden.
Also on a gyro, dual lower cables or no gyro at all. More adjustability and so much smoother/stronger/ less stretch. The dual cable setup I had was better than any straight cable setups I've had. It was odsy dual cable lever (m3?), odsy gtx-r, London mod, fly brakes.
