The handle on the FS and Whipped dog are almost identical minus the fs on the FS brush. The third looks nicest but not even a top view of the knot.. WD has decent knots but ill say this..their silvertip is not near as dense as that FS extra density knot. Id suspect it is a virgina scheng density bulb silvertip. If it is it is better than the standard WD silvertip for sure. Id go FS. Also if i got a WD brush Id get the knot and handle sepearate and knot it myself. The last one i got the knot was set crooked. Drives me crazy everytime i look at it.
