904 rebuild parts & pitfalls

Ok, got the tf2 kit installed in the VB. Got the transtar kit, Sonnax servo, and springs & rollers. Should I upgrade the clutch packs to alto reds (kit has borgewarner)? Or should I go to the 5 clutch pack by using the thin .061 disc with .068 steels? I also contacted CRT and they recommended the following parts, what do you guys suggest?

band strut

low reverse band

2nd gear band
