strawberry plants

Don't know I only have grown elsanta which are lovely.

I've done a bit of googling to find out when they were developed:
Christine 2002
Amelia and Sallybright 2007
Malling Opal 2006

As they are modern,  they are not on my must have list, however being so VERY recent, I would give them a try if someone gave me some.
The ones I am trying to avoid are the ones that were developed in or around the 80's.
The last three varieties in the selection, were developed by Malling, so as they develop varieties for the home grower (as well as commercial ) they could be good.
I didn't manage to find out anything mcuh about Christine, other than it's very early. At the time it was THE earliest.
Oh and Malling opal is an everbearer, and Amelia and Sallybright are mid June varieties.
