What's the smallest ID hard line that would be appropriate for the brake line runs from the pedals to the wheel wells?  I have some 1/8" versatube that I bought for this purpose way back when, but I'm afraid that #1 its working pressure is too low and #2 the .069ID may simply be too small to allow the brakes to respond to pedal inputs quickly enough.  There's hardly any weight increase going to 3/16od, .135id, so that would be ok by me.  Also, instead of the versatube (3003) would it make more sense to use 5052?  Stainless for the interior runs seems like way overkill.  Thoughts or comments?
