Drilling is always the best way but in my case its now an option. Im going on a trip and was going to slap the wilson on, either magnet or trunk lip since i have both but this thread is making me think to grab a sirio instead. Saw them on h&y for around $60 so was thinking, what the hell!
let me know how you make out with that mount. especially around the performance difference between that and the sirio magmount.
