last gasp of GBP strength

I believe last leg in GBP strength has just started before a major GBP reversal in next few days. I believe GBP will appreciate against all currencies. Given position USD/JPY I am not long only GBP/USD but mainly GBP/JPY. I believe it is a better pair to trade now then NZD/JPY based on attached GBPNZD scenario.
Tomorrow there is a BoE minutes. I am expecting firework and even possible reversal in GBP/USD and/or EUR/GBP (GBP/CHF).
