I once got TL700 as a stock when BA used to be in Toplace.
It was the most undetectable piece that i ever used but shed like crazy and was unwearable in 3 weeks. I remember John saying that he gets 4-5 months out of this , so maybe he can throw some light. Also, i dont know if the TL700 available today is the same as the stock that was being shipped out in 2009
