omega 10077 or the vulfix mixed, both are under a £10 and will bloom naturally after a few uses.
With regards to bulb and fan, one thing has to be remembered were dealing with Shavemac's 2 band silvertip. This is the best badger hair I have ever had the pleasure to use and own. Infact I now own three and waiting on my fourth. The hair is so soft with very good backbone, in other words the fan will be soft and the bulb will be soft to feel on the face. The bulb feels more plush having less surface area at impact, whereas the fan feels more like the plisson (cloud like) with backbone and with a more natural bristle feel (more heat and water retention). I cannot say if I prefer either with regards to this brand, I alternate and love using both. No sharp point on the bulb but obviously more accurate in lather placement, being top quality the fan doesn't just make a mess on your face either. What stands out is the balance of backbone to softness of tips. No scratch, scratch or prickliness. Bernd has hit the ball out of the park with this one. Again with other brands the knot keeps its shape better as a bulb but again IMO Shavemac knots are superbly neat after 20 or so uses both my bulb and fan haven't distorted.
Badger hair has so much more IMO than synthetics, such as greater water and heat retention, also with synthetics you can get a cloud feel if the bristles are thin (think Plisson) or more backbone feel with thicker bristles (think Omega S). However,trying to get the required backbone and softness without compromising face feel (having already lesser heat and water retention) is difficult with synthetics IMO. You could argue that increasing the density of the thinner bristles will correct the above (tried Sterling's and IMO this is not the case) but it just alter flow through in a not so positive way. Badger all the way for moi
