I'm looking at doing similar with 930 I got cheap recently. Did you end up going with a rigid fork? If so what fork?I agree. Having revisited m739 groupset last night... m739 functionally over m737. Would consider the m739 brake and gear shifters to replace current sram with m737/ m739 rear mech and front mech.
Rigid forks for the trek 930.. which ones? Will go rigid.
