I've never had a problem masqing after flying kick, since generally your cursor is already on them when you f k so you can masq straight after. If it's an issue for you try using transformation scrolls to reduce your sprite size so you can click on your targets easier.
Rapid throw hasn't been nerfed yet (update incoming), it can still kill occasionally but the new level cap and higher hp pools does mean it's not as strong as it used to be. It also has a horrendous success rate and long cooldown.
SF + traps is ok in pvp but it takes time to set up so if there's a lot of people running around you're probably not going to be able to pull it off without being attacked.
