i've had so many possibilities of what may/may not/should/could/might do for this it's getting a little confusing
i've drawn every option as guys have mentioned it and all have some form of merit...suppose it's what you feel best trying to explain and if someone else comes up with another concept that you prefer you'd probably go to that one... i'd just like to know EXACTLY what causes it
, just incase the examiner asks me...just so i can be ready for the slippery old goat
