There are alot of great artist that use the turbo and nothing but, Myles Pinkney

for one but if you check his turbo out he has spent alot of time setting it up so it works as he wants it to. He has replaced to handle and done alot of other mods to ensure it stays adjusted. So it can be done I just haven't found the time to do it with mine, someday as its a very cool brush to use. Check his work out.
