>>7617246H&S brushes are well made and you feel it when using them. Got the Evolution Silverline 2in1 myself, it really is worth the money.
For Vallejo acrylics, in my experience they go on well but be prepared for tip dry and clogging every few minutes. IMO Tamiya sprays better. Get a flow improver and retarder if you absolutely want to use vallejo for airbrushing.
>>7618209I've found Vallejo Satin to be one of the better topcoats, it also sprays better than their other airbrush colors.
