Well done!
I am a recent convert (about a month in), I can't comment on Boots razors, as I splashed out and went for an Edwin Jagger DE89 as my first razor.
I have tried lots of blades now (including the ultra sharp feather blades from Japan), in the end I settled on Astra Premium Stainless, as they are almost as sharp as the feather, but a lot smoother on the face, and you can get a hundred on Amazon/ebay for £8.
If you are getting niks have you tried rubbing a wet alum block over a wet face after your shave, it stings a bit, but if you let it dry and then rinse off with cold water and then apply some nice aftershave, I find the niks just vanish.
Glad you are enjoying it, shame it took me so long to try DE shaving, I will never go back to Fusions et al again.
