The UK is one of the safest places to bring reps into. Some TDs triangle ship via the UK for that reason. Indeed Sead (Supermirrors) has UK stock and is a great guy to boot
I have only had one with a Prof Cyclops, but sometimes the blue tinge on a Cyclops gets to me, but that is rare. Believe me I am no AP expert lol. I just love the Leb as is. APs In general I do not do too much messing with, primarily because I do not know enough lol. .
I do not think the gen xtal is as clear as a Prof. But that is just me maybe. Prof xtals really show off I have had a few 44mm with them. I love them they are see through with no colour tinge but I do like the JF and Noob xtals, the cyclops could be better though.
