Most 4 tracks prefer CrO2 tapes like Maxel XLII ( also XLIIS )
One rule of thumb, as told to me by a long time 4 tracker, look for the darkest tape. As near-black as can be.
If you look closely at a Normal tape, it will be a medium brown ======================
If you examine a CrO2 tape it will be very dark brown or almost black ======================
Sony UX Pro cassettes are very good. Have used them for a long time; however, they are a bit difficult to find. Maybe search on the net? Since I moved to digital, I don't use as much tape--my sale's person gave me a gaggle of cassette tape a while back and, in turn, I gave away some of it.
