Test rode the gtl and rt back to back. I found the rt had a much smoother flow of air and little turbulence at speed. However, I found the gtl more comfortable for me. I would prefer the gtl if it had as good wind protection as the rt. With the aeroflow package can this be attained. Rt with windscreen half way up was so smooth and I was looking over the screen. Thanks for any help. Just don't want to spend a lot of money on gtl and not be comfortable getting beat up by turbulence.
