No, but I dry hopped a 'normal' brew with 50 g of Admiral and wished I hadn't! It came over with very very strong resinous tones which took about about 2-3 months to mostly wear off.
Maybe it's a Marmite hop?
A while back a forumite who no longer posts sent me his supply of Admiral because he hated them so much. I just used them for bittering so cant comment on their late hop aroma/flavour
