I have my E7se on order now, just waiting for a new shipment from Matt to the UK for mine.
I have 8 x 12s sticks that are 6s5000 Optipower packs shrink wrapped together. As I have a Goblin 700, Goblin 770, TDR and T-Rex 700 DFC all using sticks, I opted to make my sticks out of Goblin trays. This is a carbon top and bottom sheet with shrink wrap holding it all together. I then just slide them straight into the TDR and use 2 x Scorpion straps, and on the Rex I use 2x straps around the alloy sliding tray.
With the E7se, I will buy the rear alloy Goblin 'clip', and see if it does fit to the base plate in the correct position for C of G, then that way I can hook the goblin tray into this clip, and use just one strap like we do on the Goblins.
