| Hi, I have used V-Two adjustable pulleys on my 851 special, i found them very easy to set up and appear to be very well made. Offset keys are 'mucho' expensive and quite hard to get hold of (in a hurry) they also come in 2 degree steps,so are harder to get spot on! The only way i can see them failing (the v-2 items) is if they are not installed correctley, maybe coming loose. If you know what your'e doing this shouldn't be a problem!
After setting your'e cams with the v-2 pulleys,there's a small hole in the outer face of the wheels,using a small drill, 3mm? you drill through the whole unit and then install a stainless roll pin,then the wheels can't slip/move. they can still be dismantled and reset in the future,by removing the pulley and knocking out the pin.
In my opinion both v-two or sigma don't sell **** or bling,i have always beem well pleased with their advice and their kit.

I carry out all my own work,but if i had to choose between sigma or pro-twins,then sigma would get my vote, based on conversations with both outfits and surfing the net.
