Hey I was wondering if anyone has any thoughts on this pack now that it has been out for a little bit. I have been looking for a good day pack with the ability to haul out some meat if necessary and this seems to fit the bill. I have been looking hard at this and the tz 2220. Any pros or cons? Is the tz 4000 worth the extra $150?? I am a stockier guy at around 200lbs but not too tall at around 5'8". Would both of these packs fit alright? I did get to try both packs on at a local store and they fit fine but obviously I did not get to try them with any weight. Thanks for any and all help!!!
