Hey Kris ,
I'm just like Ben , I don't have the "MAD" skills like many of guys here. My first brush was the HP-C Plus , which has the 3mm needle , its a Great brush. I then purchased the Hi-Line HP-AH which has the 2mm needle , I do my detail work with , as/well I have to thin my paint , due to the smaller needle. I do use the mac valve on the brush , its easy to adjust my air pressure.
Like Ben said , others will chime in , that can use any brush to paint GREAT looking baits, these guys have SKILLS that I'll never have , but have given me some great tips & tricks to make me a better painter & for that , I Tip My Hat To Them.
Mike
