Hi all, I'm looking for roll bar alternatives to the Plus 4 Sport (2011 model).

The Aero Racing option is tempting:



As well as the librands roll bar:



Some questions for the TM knowledge base on these models:

*Does the mounting of the Aero Racing option involve cutting the frame etc. like the librands does?

*Are there any known issues with either option (quality, rust, finish, fitment, etc.)

*Any knowledge on the headroom with both is welcome, measured height and position in cockpit would be great info!

*Does one or the other use less boot space when mounted?

*Will the old style (9-stud) hood function with both?

There is not a lot of info on the web for these products (except for the splendid "how to mount a librands roll bar") so any info is welcome!

Also, any info on other roll bars are most welcome, except the helmet/FIA ready ones a-la safety devices...


Here is a picture of a safety devices one (they probably have several?):
