So given that information, I suppose going with the 113mm spindle would probably be the best choice since I can then shim the BB if there is an issue with clearance or shifting. As I'm going to be putting on upgraded front and rear derailleurs that I have laying around, I'm less concerned with the derailleurs working properly than I am with frame clearance for the chain and inner chainring.
Many thanks for your insights on this.
