I gave away my spoilers. They came with a cased superspeed I bought, and I sold it with the spoilers for $20. I wasn't game to try an opened pack for 30 y/o blades. Maybe the buyer tried one in the black handled superspeed I sold with them?
I'm way past trying different blades, tried about 15 different ones in sample packs and there's too many out there and not enough storage for them all. I'm sticking to red pack personnas in the slim, IP super platinum+ in the NEW, feathers occasionally. Might get some bleues after the long life they showed with the few I got from BA. Didn't like SIs at all. Of course I use SE GEMs as much as the red tip superspeed, slim adj, NEW and new improved - got plenty of other DEs, but don't like them as much as those four. I normally only use a DE after starting with an SE and getting a bad shave, switch due to disgust that the SE blade only gave 3 good shaves again and stick with whatever DE razor I picked for the cycle, then got back the SE with a new blade when the DE blade goes dull.
