SNPA Hop Question

I plan to brew a SNPA clone next week based on a recipe from here. I have a question on hops. I am based in UK and can only get German varieties of Perle and Magnum, will this make a big difference to the taste or would I be better subbing for other US hops??

I doubt it will make much, if any, difference.

It shouldn’t make any difference, the important hop in SNPA is the cascades.

Cheers guys!
