Aggressive Vintage Gillette

Hi Gents

New to the forum - nice to sign on 

I’m relatively new to DE shaving.  It’s been a bit of a learning curve, but after some experimentation I’ve settled on a Slim Adjustable and Astra platinum blades.  My beard is very, very coarse - the best shaves I have are with the Slim turned up to 9, and let it glide through the forest.  Ive learned to wield the Slim this way and have very fine shaves.  

My question is, are there other vintage Gillette razors that may shave as well or better with my thick beard?  Red Tip?...

Thanks a lot
