Well here is an update for all you sly guy and gals.

Sly has improved my skin greatly indeed which is why i went sly in the first place. now just need to adjust the hard to sly places in the back at the crown.
i have tried the headblade but find it leaves me a little burned even with no pressure and just a simple glide.
i find my best sly so far is with fusion. i work nights so i sly when i get home. can't stand the sand paper when i get home.
