I agree the head is a bit down to what you like yourself and dependant on the head shape, my Amy has a very pronounced boney nice shaped skull put if I stripped it out smooth the boney bits deflect the overall shap so I leave her with quite a long smooth covering and donot blend her ears in
Jodie on the other hand has a wild wavy top and it drives me mad I tend to strip and thin to shape hers I leave it longer at the front (the only straight bit ) and thin out the top and shortern back of her ears to create some height. I did take it back short once and she looked awfull as she did not have a domed head unless I then thinned down the top of her ears.
Its a bit down to your own view of what you like best I prefer not to thin down the top of the ears but I now a lot prefer that look
