I was a fan of the original capsules as well, but the deformation after 2-3 re-uses really bugged me. I am using the original dosing capsule filling tool (
https://www.storz-bickel.com/de/filling-set-for-40-dosing-capsules) and plunger to assemble, however i find it hard to get them to firmly seal without getting a crooked top. So on first use i end up putting them together not too tight to keep the caps center. After hitting them for the first round they will already come out with deformations on the bottom (getting squished and twisted by closing the CU). They ARE absolutely reusable at this point, and i will do so for another 3-4 rounds.
A good compromise for a nice flush seal without deformation is to use a fresh cap, paired with a cap top that has already been used once.
Now the comparision with titanium caps:
Filling:
You can completely forget about the whole cap top fiddling around, you simply pop on the top and it sits. It does have a bit of play, but not to the point that the cap could come off by it self (even with vigorous shaking, i've tested it
)
Performance:
I feel i get a more uniform cook throughout the whole bowl. Furthermore with temp stepping it feels i get distinctly more vapour at each different temperature, whereas before the amount of vapour would decrease with each step up. With using the same amount as before (around 0.15g) i get more and longer vapour out of one capsule, compared to the aluminium ones. Interestingly after completely finishing a bowl at 210 degree celsius (no more vapour coming out), the ABV is cooked a good bit lighter than with the aluminium caps.
Cleanup:
Super easy, just swab it with some iso and you are good for refill again! Also the caps. do. not. deform. at. all. I'm really happy to have found them, as i now no longer have to rebuy the aluminiums!
I might update later with comparison photos if anyone is interested.
