What is the Best Dual ring chain guide yoke?

Wondering what the best /cheapest thing is for keeping on the chain on a dual ring setup?

theres no iscg tabs.

I just run a bash ring and a front mech does the job perfectly.

One of these.. and your front mech..

if you want to try out what mr mac has suggested I have a spare one you can rent for an exorbitant fee

thanks lads thats a help.

gav, go play with your pedals.

I have one of those yokes Mac showed - bating off Scarr last night with the suspension bucking and bouncing like a wild thing and never dropped the chain
