[Amps] braid vs bus wire

  You want something that has at least as much surface area per inch of length as the largest conductor in the coil.
I don't know what the surface area of RG-58 shield would be but you can take calculate the circumference of the 
#14 wire and compare it to the circumference of the tiny wires in the braid times the number of wires. 
  Now saying that, there are two issues that are important. 
1. Tinned wire has higher RF resistance than bare or silver plated copper wire due to the fact that the tin or if older stuff tin/lead has higher
resistance than copper or silver. 
2. Braid soaks up solder like a sponge and thus much of it quickly becomes a solder covered strap losing much of that surface area. 
    It would be best if you don't have strap available to go to hardware store and get some copper flash material
    and cut it up into strips.

Is there any reason the braid from RG 58 would not work as well as #14 solid tinned wire for connection between the pi net coil and bandswitch at 1kw level and frequencies 160 thru 10m
I realize strap is best but curious if anyone has used the braid and their results.
Thanks
