Send it out and get it honed
You picked a nice razor. The TI scales look great on it. Low spine wear and a nice clean edge.
You already shave with a DE, so you should have lather and prep sorted.
Just take things steady. Do your cheeks then finish with the DE, Then do a little more on the next shave. You'll soon be doing everything with just the straight.
The advantage or the straight is you can do longer passes, Cover more face per pass. And look badass in the mirror. You can also clean it in just a wipe between passes no more dunking and swishing about in the bowl.
You are going to need a strop, the cheapest UK one that I've seen for sale that I would trust is the one on invisible edge.
There is a standard one for £21.
And a canvas backed one for £29.
I'd get the canvas backed one.

And if you want to move over to this type of shaving after using it a few times then perhaps a second strop to be used with 0.25 diamond spray, and 0.5 micron chrome oxide should keep a single razor shaving for a very very long time (years) between honing.
