Karl, Karl, Karl,
At this stage of your straight razor journey I would suggest that you do not need any hones at all.
I have a shave ready razor that I purchased from the classifieds here well over six months ago and I have yet to feel the need to touch it up on anything other than my strop.
Granted I have restored a few since then and used them all, however, I have kept the shave ready razor as a point of comparison, so to speak, so I know how an edge should feel.
If I were you I would get used to shaving WTG, XTG and ATG and getting good results for at least a dozen shaves before thinking about honing your razor.
I would also suggest that you get a shave ready razor to use as a baseline to know whether or not you are getting a good edge once you do start honing.
Maybe in the first instance you may only need a PHIG to touch up your razors. (Glen has posted a great video on this subject on You Tube)
The choice, of course, is yours alone and this is only my $0.02.
Whichever way you choose to go, hang on and enjoy the ride.
