TGN Finest vs Finest F2-Help with selection, please

Hi!
I have a restore in progress, and I have two knots from TGN on the way. One in 20mm Finest, one 18mm Finest F2, which TGN states is "taken from the Manchurian badger". I know there is a good portion of the wet shaving community who are enamored of Manchurian, but honestly, I don't know enough to understand the difference.

Badger Hair Knots - Wet Shaving

The difference in size makes zero difference to me. I like smaller knots so anything in that range is fine, but the diameter might affect things like loft in regards to the characteristics I'm looking for. I hope this brush will end up being a favorite of mine, and one I can find great pleasure in using.
Both knots are 60mm loft. I bowl lather, so thinking of a final loft in the 50-52mm range. Not looking for flop. I want some backbone, but I would like a bit of splay on the face. Mostly use soaps, but some creams.
Taking the information above into consideration, those of you who have experience in both knots, I would appreciate opinions and suggestions, and also feedback on the loft height I mention for these type and diameter knots.
Thanks.

Went with the F2. Pre-bloom.

Hello Mike. Glad to see a few straight shavers are making brushes. You get so much more bang for the buck. I see a lot more choices of knots available than when I made a few a couple years back. I still have 4 knots waiting to be assembled. I think you made a good choice with your knot. I think my favorite size is 24mm although I still like the luxury of the larger sizes from time to time. This makes me want to wander the antique shops for old brush handles. bj

Thanks.
Yes, it is very rewarding. I've shaved with this brush for 6 days, and like it more and more each time. I have more of an assembly than a restoration lined up soon, but I want to give this brush a good evaluation before I put another one together.
I will eventually take everything I learn from the brushes I build, and put together what I think is the perfect brush for me. And it will be easy. There are a variety of handle choices, if you include the guys willing to turn one for you, and they are out there doing fantastic work. And that presupposes I don't start turning myself.:roflmao
