hi Mike,
	I'm not sure how many. For instance, if there are 2 lengths of 18 each, maybe 
having 2 spares of each length is a good plan. If there will be 6 lengths and 6 
each, maybe 1 spare of each? Or we could have a plan of holding only 5-6 spare 
half-cables (D connector terminated, longest length) and spare T-boards and cut 
and solder those at BNL only if a spare is needed. I think that wouldn't be 
unreasonable since the spares will be used only during extended downtime when 
the detector is withdrawn from the cone. How long do you think it would take you 
to terminate to a T board? Maybe 3 hours or so is my guess.
        Sincerely,

                Gerard

p.s. On Q1 I think you should get at least one now and see that it fits well 
with the cable. After that I'd get the full quantity,  once that's defined.
