I'm using the sideslip trick i was taught nose into wind kick straight at the flare,
If you are sideslipping, i.e. wing down, the aircraft should already be straight! If you are crabbing, with the nose into wind there is no side-slip, the difference between track and heading being drift.
kick straight at the flare
You should not kick anything, maintain directional control with the rudder, you only need to align the wheels with the runway just before they touch it.
If you have a strong X wind (not 6 kts) the last thing you want is the aircraft drifting sideways over the runway before you touch down, full or land flap is put there to provide additional drag at that critical moment to minimise the time spent floating sideways, why throw it away by reducing flap settings and increasing the landing distance.
