TSA locks are total crap. Anyone can break though them in a matter of seconds. The only time a lock needs to be a TSA lock is when going through the line at the TSA.
What about the rest of your trip, don’t you want something a little more secure for the entirety of your trip?
The Abus 75/30 is my go to lock while travelling. Small enough to work with most travel bags, but hefty enough that no one will mess with your gear.
