I still land a little flat in the PA28 but this is possibly due to the fact it is a heavyish aircraft for me, I do however get the odd landing that isnt that flat so i know i can do it. I was landing flat initially in the PA38 as well but with work I started flareing though as it is a lighter aircraft I have a tendancy to balloon.
I am begining to wonder if I will ever get solo in the PA28.
As for examiners not all CFI's are examiners and whether you will be examined by yours depends on how much flying you have done with them and how recently. Dont worry about examiners they are human and those I have come in contact with are very nice.
