I have only two of his designs, so I guess that is pretty easy for me.
#1-MOLLEX-I have to admit that I was a bit skeptical when I first got the pack, I didn't think it would be big enough. It made me re-think what I take out to the woods and then I started to add pods to it and that was a game changer. I have a large and a small pod, plus a cargo chair. The Omni waistbelt is what legends are made of. I don't think I will ever not use this pack. The versatility alone with this pack is worth its weight in gold.
#2-MS Day Lumbar Pack-I have had this little dude for almost five years now. I bought it with the strappettes and recently cut the wing style belt pieces off and replaced with a MS pack waistbelt. It connected right up and makes this thing even better. I have this on the trading post, but I am not really sure if I want to get rid of it just yet.
