Varial 2011 and 5 lines bar?

[christophebcn]

Hi,

Could anyone comment on using a 5 lines bar on a Airush Varial 6m 2011?

I know it can (should?) be used with 4 lines, but the bar for my other kites is 5 lines.
In addition, i use the 6m when it's really strong so i wouldn't mind having the peace of mind of a 5th line...

The manual seems to be the same for all 2011 airush kites, and shows both 4 lines and 5 lines smart bar, but it doesn't specifically talk about the varial...

Can i connect the 5th to the pump attachment (i guess i need some sort of extension)?
Is the pump attachment designed to support the 5th line load if i release?

Thanks
