Starting to think I will graduate the whippings from black at the butt to very light grey at the tip. Possibly play about with a butt fade as well (that's sounds so wrong!).
Orrrrrrrrr, I may go transparent whipping with a 3 - 5 turn trim in black only. Trouble with transparent is that the guide feet, for me anyway, will all have to be trimmed back and shaped so they all match, and then re-painted. I hate to see uneven feet!
