100x Shark Saloon single edge Razor Blades

I am a rookie straight shaver, so tried these and the Derby saloon blades as I had heard they are quite forgiving on the novice. Have to admit I prefer the Derby blades, which are nice and sharp but don't feel dangerous (although there is still the odd nick). The shark blades I felt pulled slightly even on the first shave, so felt like you had to put a little more pressure into the stroke. The second shave with a shark blade felt like the third or fourth shave with a Derby blade. Which is a shame because on a purely superficial note the Shark packaging is pretty cool! and gives it a bit more of a retro feel. If you have fine stubble then these blades might be ok? I reckon it's still worth trying a few to find out which suits you.
