Rapping off a V-Thread with different diameter ropes

Hey Martin.

Today I read this online 

"2 different thickness ropes go through the belay device at different speeds and there will be sliding movement on the lighter tag line which could melt through the v thread cord.''

Is this a legitimate concern while rapping off a v-thread? V-threads already are scary enough while ice climbing and this complicates it more.

ERK,

Yes, that is a valid concern when rappelling off a v-thread without metal (rap ring, quick link or carabiner) at the connection point.  It's quite easy to burn through a single v-thread (or even a double v-thread for that matter) if the ropes start to shift.  

Jeff
