Another thing... Feather is ULTRA sharp, sharper than anything any honemeister can come up with and that changes the technique a bit. With a straight you do have to apply more pressure but don't overdo it either. If you apply the same amount as with the Feather, you won't cut much hair and if you apply too much, you'll irritate your skin.
Even though you have Feather/DE experience, to get a proper straight shave, when using a straight, proper technique is even more cruicial.
