I think the old design is a lot cleaner and practical. Having scroll bars in some torrents with long descriptions is very awkward and in general seems like the list ítems in the search are very bulky which makes you scroll down a long long page to see the same amount of results as before. Also, the Font is too big for my taste, just an opinion.
The Torrent detail pages seem alright, I don't know if there was a change there, however the search page is not very practical.
Hope this helps.
