When I order from GZK it's always enough to get free shipping. I usually order a 100 meters of tubes at a time. And he always includes a bunch of free stuff. Flat band material, pouches , tying ribbon, etc.I got some SS 1632 too. I like it well enough but noticed it goes through a growth spurt in the first 100 shots or so. I cut my normal length and they feel good for about 100 shots and then they get way too long, which forces me to cut my pouch off and re-tie to shorten them about 1/2 " to 3/4". After I trim them down they seem to hold well.
It might not be a popular opinion, but I still feel the GM&BW tubes are the best for me. I haven't tried GZK because I'm not going to purchase from somewhere that forces you to buy $60 worth of stuff just to get it shipped.
I just ordered some tubes from Spearit to see how their tubes compare. Pretty pricey stuff at about $1 per foot, so hopefully it's worth it.
