Well, a sniper has a quicker walking speed than a SinX since they have wind walk on their side.
Taking that bit of information in to consideration, it's just a matter of fact to know about this:
Majority (90%) of the players in RO will chase someone from the butt.
Many SinXs fall in to that category and therefore they will chase you with cloak up the butt. All you have to do is windwalk, run a straight path and place a Sleeper and ankle snare if wanted backwards.
If they're immune sleeper, feel free to just stun with land mines (they do a considerable amount of damage as well if you're on FA build... approximately 1.2k+ per mine) and FA them every time they reveal themselves after taking a hit from a land mine.
Obviously they can out-pot that, but in a duel with no pots, you'd be declared the winner.
(If there were pots, then you must have to be lucky and hope that they aren't immune to sleep. If they aren't, make them fall asleep, drain their SP, place a sleep trap that is ready to be pushed by arrow shower, use FA and immediately put them to sleep before they can pot a lot. OR, just sleep/ankle snare and stack a lot of land mines and try to kiss them goodnight.)
