BSP caps are thick and their doubleshotting was as good as the big boys, they just didn't want to invest in new molds so community interest died. Then they stopped production.
I have a sample pack here so can confirm they don't hit 3mm round LEDs if that matters, the texture is smoother than DSA and they have larger top surface.
If I liked the colours and wanted ortho I would happily buy the set.
The linked set is sold as Cherry profile not DSA - I have no experiece with BSP's Cherry profile but expect it's lovely. Cherry profile means different row heights/slopes so if you want flat DSA style they may not be for you.
