I bought a Kent Blk2, for the money, it performed worse than the $20.00 brush I got with my starter kit. Floppy would be the exact description of it, and I hate floppy brushes, I prefer more aggressive brushes with a stiff backbone to them.

The boar brushes, specifically the Semogue 1305, was nice to try, but just doesn't fly with me.

If I were you, I'd first figure out exactly what you want in a brush, and PM one of the brush makers on this site and get a custom made. I know "pixelfixed" and "Walleyman" make some pretty fantastic brush's, and they will make you exactly what you want in a brush...I have one of Walleyman's brush's...and am most likely going to beg pixelfixed at some point in the near future to make one for me....in my opinion, that's your best bet...can't beat custom when it come's to a brush, IMO of course.
