As far as we know the only difference between the two kits is no helmet or boots supplied with the Standard (due in August). We can only assume the armour will be the same quality.
The Premier Line helmet runs at $600 on its own. Boots are around $150 delivered from IB. Can we assume a standard kit will run $1200-$1500? If so, I personally would be waiting on that and buying a Standard bucket. I've heard a fair few stories of people who prefer to troop in the Standard helmet ($250) vs the heavier/hotter Premier Line.
After all this you also need to keep in mind expected vs actual delivery dates, and costs of shipping/customs.
Just my two cents [emoji16]
