...from a relative beginner...
Blowhard2...
I am a novice when it comes to straight razor shaving (I have had mine for less than 2 months) but have learned quite a bit about what NOT to do. First off, do yourself a favor and get your razor honed BEFORE using it. I got a TI and thought that it came "shave ready". BOY, was I wrong!!! I got a nice cut (not quite as bad as the example we just saw, but fairly close. I felt like I was shaving with broken glass. I tried to hone it myself (a little better, but still VERY uncomfortable), then finally sent it off to Lynn. When I got it back...MAN, now I know what a shave ready feel like on my face. That knowledge is invaluable. I have since bought an eBay special to learn honing, and have been able to bring it up to a nice edge (not to the level of Lynn's, but shaveable).
I bought Lynn's video and it is WELL worth the money!!! So much information packed into one DVD!!! Not only will you learn about how to hone and shave, but he gives tips on what to look for on eBay.
As far as brushes, I have been using one for most of my shaving life. For the longest time I have a williams and used williams soap. I learned about this from my Grandpa when I was about 16 so I have generally enjoyed wet shaves (except for that BRIEF insane period when I actually put a mini-lawnmower to my face!!!). The boar bristle brush will be mush better than the williams which is just "bristle", and that worked nicely for me for many years.
When the folks talk about SRAD, they are SERIOUS!!! Since my initial investment of the TI and nice strop I have purchased norton combo stones, 3 eBay razors (and looking for more!!!), a lapping stone, a silvertip badger brush, various soaps/preshaves/aftershaves and polishing creams. It is thoroughly addicting. As far as the total cost, I figure that I used to spent at least $250 on mock3 blades a year (I can't STAND them dull and wnet through at least 2 per week). That being said, I still haven't spend that much on all the stuff that I have bought thus far.
Another thing I might suggest is to watch the National Geographic Channel special about shaving. It gives you a great deal of insight into the science behind what makes for a great shave. It is under either the "Shaving" forum I believe (someone please correct me if I am mistaken).
Have fun and take your time.
