If any of you fly outside of the xwind limit, you are not insured at all. Do you fancy a bill for the aircraft, loss of earnings, airport crash if they are mean etc...
The crab techinque is ok till ground effect, then aim to drop the wing very slightly into wind to stop the drift. The risk of keeping the crab on till the last minute is cocking it up and exerting a side load, especially in a retractable. Rapid changes in rudder input require opposite aileron. This causes drag on all surfaces, mainly the lifting ones giving obvious downfalls.
If in a twin, do not put on too much bank or risk a prop strike. This is called the 'combination technique' and is the more commercial way of doing it.
If approaching in gusts, add half the gust factor to your normal approach speed eg wind 320 20G30 gust factor is 10 kts. Half is 5 kts so add 5 kts. BE76 short final is 85 so I would fly at 90kts to the threshold and add 5 kts to that giving 81kts. Check also you gust limit eg max of 30 with no Xwind Component.
These numbers all come from the Vmca speed and adding a factor to it. Vmca being the speed at which you have control in the air of your aircraft. It is a control and stability speed NOT a performance speed, so don't expect and favours if you get that slow, which a gust will do to you.
With the wing down method, you can, with skill, exceed the limit, bit it is very foolish. Don't forget that if you add roll and introduce a sideslip that you will get tailplane stall as the angle that it is introduced to the relative air flow is like sticking you arm out of the window, so a positive arrival may be needed, one wheel only very slightly before the other.
If in doubt, some instructors don't remember a great deal as you have to keep reading all of the time to remember it all, so you may not get the whole picture. Get a good book and learn why things are done. It may save you life and your pax.
Try and anticipate how much control input you need to reduce a draggy unstable approach...bad for you and worse for your pax.
