Hi Mark,
             Use the U3 damper set as that will give you the nice triple wedge
dampers, and cut the over ring to almost nothing
The damper blocks I run through the band saw with a  fence so that you will
end
up with a  basic damper shoe about 1/16" thick. Glue a felt square to the shoe
to act as a hinge, use the the dowel type damper fittings to glue to the
felt. 
I use a generous dollop of white glue, it seems to stay nice an elastic, and
does not wick into the felt as much as some other glues.
One tip, make sure that the top of the damper head is tipped very slightly
forward to prevent the bottom of the damper from dragging on the string on
lift.
I have used the over dampers for the first 3 notes of the tenor and it takes
quite a bit of adjustment to get them just right, also used tri damper felt
with satisfactory results but not quite as good.
Go for it you will probably love the results, remember to braid the back scale
area of the bass and tenor.
Hope this helps.
Roger
