I've used a Boar Brush (Omega) since I started DE shaving in early October, 2010.
It picks up soap and or cream great, lathers very well...it was about $ 10 or so...but I'm very happy with it.
I've got a Badger brush which so far doesn't pick up soap and or cream well, nor is the lather as good, as what I get with my Boar brush.
It cost a lot more than the Boar brush and I've read in this forum that a Badger brush is the brush to use.
I've only used my Badger brush since December 25th...so only about 3 weeks or so.
What I'm wondering, does it take awhile, does it take a period of use before the Badger brush is up to snuff ?
