comfort and comms for me.
Like all have said keeps wind and spray out of your face when its rough.
Also how many of you have to stop or slow down to use your radio?
With an intercom system we can chat to the crew without shouting and use the VHF at full speed.
Also mean my hair sttays nice
Safety is a valid point, I am sure there are lots of times where what happened to Richard happens to us all, if not we have had a near miss.
I know lots who have lost teeth!!! but not when I am driving
Simon if you scoll up you will see mention on the Gecko comms kit.
D S Dev also make one.
I was just offering to mod the one Dan already has.
