I've been cycling through soaps lately myself and have found that my favorite soaps todate are any in the Trumper's line of soaps.
I have several Honeybee soaps (Lime, Forest Pine, Vetyver, Oakmoss, Lavender, Violet) . . .Honeybee wins out for me, because for less than $4 a puck, you can't beat it. And she has tons of different scents. I love her pick three deals. I'm trying to decide what next three to get.
Wanted to update my preferences with a new contender: SCS New Spice soap. I got a sample of this in the B&B Newbie Sampler kit and I used it this morning. I could not have been more impressed...it lathered up quicker than any soap I've tried (rivaling the speed of the best creams I have used), it easily produced enough lather for my normal two full and one partial pass (with a ton of lather left in the brush that I had to regretfully rinse down the sink), it offered terrific protection even to my lower neck (which usually gives me a problem with almost any shaving product), and it had a nice, pleasant scent that hung around during the shave and didn't linger afterwards.
I absolutely LOVE the Provence Sante soap, recently telling a friend it wasn't just the best soap I have used, it might be the best shaving product, period, I have ever used. I will have to use the SCS soap more than once for it to overtake the Sante as my all-time fave, but first impressions indicate that it could be a close race.
