I also switched in Gale Force for Time Shift
Priority was (weapon, Gale Force, frost, lightning, fire)
Oracle gun, 227.8 Damage, 11.13 crit, Clyde = 371 (10 more dps over TS)

Gale Force does the least net damage per spell cast (including upgrades), so it probably should be be last on priority, but because you can cast it almost 2x Timeshift, it does beat out TS on total DPS by a bit
