[Elecraft] OT: J and -31 mix toroids

[Julius Fazekas n2wn]

I know there are several folks here who could answer this questions.

I'm looking to improve my current chokes for my 160 and 80 Tx antennas. I was planning on going with -43 material, but after reading thought -J and/or -31 mixes might be a better solution. 

The 31 mix seems a bit more difficult to find "cheep". J material is a bit more common on the excess sites. Would I notice a difference?

Currently, the 160 antenna is a Tee Vertical. 80 is a dipole, but looking at adding a Delta Loop now that I cleared out some brush...

Thanks in advance...

73,
Julius
