Hi Jaime1979! I researched 171 and found a few interesting things, the kind of stuff that gets my attention. I hope it works out for you. Just because of the recent history of Sync numbers hitting boxed, I would want to cover the other 171 combos (711/117) one way or another. Here is the chart that shows the syncs plus a couple other interesting items I found.
