There is an SLS version but Duotone are keeping their cards close to their chest and even named the board after one of their foils ?? so Google duotone Blitz and that's what you get
I pre-ordered an orange Blitz 104 DLab from a shop in the UK at the start of December. Bit of a gamble as there is so little known about it! Still waiting. One of the staff phoned me to check in with me and I hadn't been forgotten and that the whole MTO DLab is a pain. Apparently boards they ordered have been sent to German shops even though the Germans ordered at a later date - not sure how they know of this. He did say some SLS boards had arrived. It didn't sound as if they had been expecting them. The lad in the shop told me he was excited that his board had arrived but when he looked closer it was an SLS version.
The week after they phoned again to say a purple Blitz 104 DLab has rocked up at the shop unexpectedly so they have kindly offered that to me to use until mine shows up - I think they're embarrassed about how the orders are being fulfilled.
Before the shop told me SLS had arrived, I only knew of an SLS version via this article
www.surf-magazin.de/en/windsurfing/windsurf-boards/freerace-and-race/new-freerace-board-completely-new-speed-ranges-three-questions-about-the-duotone-blitz/Surf magazine did have a recent insta post showing boards on test and one was the Blitz. Hopefully that will be published soon...
