Krytac Vector - hop related recommendations needed

[sonofsammo]

My Vector is poorly.
I need to get a new hop unit, cos the old one broke. 
And previously it was flat hopped, but I don't fancy paying another £40 for that, so I'm looking for nub / rubber recommendations that work with everything else that's stock.
Any help much appreciated.
TIA ?

£40 for a flat hop!?

Just shove a maple leaf macaron and omega nub in there.
