Too much hoppage for me in this style I also believe no crystal was used but hey ho with modern adaptions.
The one thing I would consider is that English IPA's allegedly were transported for up to 3 months so that would give it time to mellow maybe as Target can be a harsh bitter hop too
I'm a great fan of Challenger, but it doesn't add much to the nose - dry hop if you want a hoppier aroma, but I often use the Challenger/EKG combination and it works for flavour.
Well I've just tried it, and it is very dry fg is 1.007, ABV 6.6%. I don't think I will bother with the dry hop, it is very drinkable. Next brew is crossmyloof Pliny the elder kit
