Yes I would say it is worth your while ... but what to compare it against I'm not sure.
Obviously a PPS blend but I think the likes of Jamesno 12yo is a richer heavier whiskey. There's not grain in Writers tears and it again makes it a bigger bodied whiskey. So what to compare it too maybe a Crested Ten. But to be honest I'm not sure really as I have not done any comparisons yet
... now you have set me a challange ... aaggghhh I'm going to have to have a few whiskeys tonight ... your a bad influence Iain
