hi ive just planted out musselburgh if any help

Try "Autumn Giant 2".  I'm trying "Below-Zero" too, this year, as it is reputed to still be harvestable until May, but obviously don't know about the taste of that one yet. 

Ive planted musselburgh too,this is my third year growing them, great taste and they last right through winter.
