I know all the AG's have been well discussed but I got an e-mail today from the B-Safe boy's offering a free demonstration. I wouldn't mind a wee go at it just to see if it is a better option than the step but all I see is the same problems like how do you fit an AG to a 13' tower without chest high scarfs and how do you do it on roofs? Is there many guy's using this system or did it all blow over pretty sharpish when they seen the cost?
