Whatever works for you really but landing performance normally dictates my technique.
I fly Dash-8's and on a nice long runway, say Gatwick or Manchester, I approach the flare at Vref 10-15kts close the powers during the flare and settle her on nicely 9 out ten times.
However operating heavy into short runways like Enniskillen, Sheffield or Plymouth performance dictates that you have to approach the flare at full flap Vref plus zero so closing powers means falling out of the sky so it becomes a tricky co-ordination exercise to close and flare at very precise moments... .success rate for a smooooth touchdown: 2 out 10 times
