Foreword: Don't rely on the caddie - never!
First of all be sure not to use the Starter wedge in your bag - consider to replace it by a decent custom wedge, distance fitting between your LW and PW.
From 20% sand, almost all clubs - ehm, irons - may work. Consider some reduction in length.
From 30% sand, the wedges below PW are best IMHO. Full shots may be 30% shorter, punches only 15-20% shorter. My custom shot from green bunkers is a LW punch (41 yds nominal length) with full backspin, minimum 50%(!) for 11+ yards, 100% equalling about 30 yds. Flops are possible but considerably shortened, sometimes even pitches work if the fringe is low (e.g. BPB #3, front bunker).
From higher %%, I'd use full shots(?! and punches only.
On STA and RSG, there are some lies in the bunker wall => punch out sideways or backwards.
High %% and orange/red lie in UEL, pray.
