I bought this pack and I truly recommend it. Almost all cleans are top notch (Roland and THD are not usable IMHO). The best thing - theses profiles contain amp plus cab, so since in use is only Aida (no cab) the CPU is quite low, something between 40-50%. YT samples are quite poor IMO, but the sounds in real use are very dynamic and all of them has its own flavour. They stack really nice with MOD Buttler or TS drives.
I have noticed that they added also an high gain and a crunch pack
