Most guys use danelle 210 for most their ties all sizes unless you want slightly thinner thread which 140 be slightly thinner,,,,eyes depend on what mold uses,,,I’d say between 3 mm - 4 mm and if wanting something slightly larger go 5 mm,,,hope this helps,,,and yes Renzetti is a fine vice if wanting to spend alittle more money, but really isn’t needed for crappie jig making…basic table vice works fine for most guys,,,rotation isn’t really needed….
