Straight, you will never see me drink a single malt with anything but maybe a little drop of spring water.
On the other hand, i do ocassionally drink JD with Ruby Port, it sounds ridiculous, but when a mate introduced me to this strange mixture i was hooked. You should all try it, its equal parts of Jack with Ruby Port.
Apart from that, I have a bottle of bacardi white, which i find abslolutely undrinkable so i just put it in my coke to get rid of it.
Another blend i had gotten was MacArthurs, a nasty gnarly vile contraption, which was not even fit to drown in coke, I managed to drink about 1/3 but the remaining crap went down the drain, and it was a litre bottle too.
