I've tried the Ringo and Delay's pack and Pawsome at one point, however, I've never tried Theirry's pack before. When I tried Pawsome for the first time , I switched back because the item pack was giving me a few glitches. Thus, I go for the most popular pack so that way I can see people's items and they can see mine without me having to guess what's really what on a person. No more Minecraft heads for me!
