See you're in Uxbridge. Are you coming to Brunel?
There have been quite a few topics on this over the years and a search would prob yield some very useful answers, although you might find them in the Ground Studies forum as opposed to Questions.
General impression seems to be that it is very much down to mixed individual opinion as to whether it will help or not.
All the best and good luck with whatever you're doing, and if it's at Brunel don't hesitate to drop me a PM.
Your friendly african dude!
