Curious too. My Blast 145 with the LTS (I think?) construction has been bulletproof for the most part after me learning to plane and foil on it...

It was way sturdier than the equivalent starboard construction

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

Surf magazine did have a recent insta post showing boards on test and one was the Blitz. Hopefully that will be published soon...

ah, thanks for sharing. also still waiting on my (dlab and sls) boards in the US, but we're typically behind...

slightly off topic: also saw that some French shops had the new X Pace, which also isn't on the website yet. should be a nice sail for the Blitz if you're looking for something without cams.

Took the offer of loaning the different coloured Blitz 104 and I will probably keep it rather than wait for the other colour - the colour is only on the tail.
Went out on it yesterday. No experience of the Blast, my usual small board is a 105 FSW and the only other small freeride/freerace I have used is the Severne Fox during a weeks holiday almost 5 years ago so it's hard to say how it compares to anything else. I thought it accelerated quickly on to the plane and when a gust hit you could feel the board accelerate. The deck shape was quite cancave which felt odd tacking in a bowl initially. Carved nicely too. Came with a Duotone Prepreg F-Ride 36cm fin

I’d love to get your advice. I have a Blast 117 (the model that the current one replaces), which I normally use with a 7.8 as my biggest sail. Recently, though, I’ve realised that I get planing pretty much at the same time with a 7.3, and I actually find it much more comfortable to sail. So I don’t really feel the need for anything bigger.

I weigh 62 kg and I’d say I start planing with the 7.3 at around 11–12 knots.

I’m thinking about replacing the Blast with a 104L Blitz DLAB and pair with E_Paces 7.3 and 6.2. Do you think that would be a good move? Would I lose much in terms of getting up on the plane early?

Thanks for the help! The wind range for my current big setup is roughly 11–12 up to around 20 knots. I have a feeling the 104 would be more enjoyable for my weight most of the time, but following your advice, maybe I should stick with what I’ve got, as we get quite a lot of marginal wind where I live.
Roughly what wind range do you use your Blitz 104 in? Since we weigh the same, it would give me a good idea of how you’ve put your quiver together.
For now, I’m sticking with my E_Paces. I’m tempted by the X_Paces, but it looks like they’re only compatible with RDM masts. My masts are standard diameter/SDM.
