String gauge recommendation

[The Twickerman]

Hi folks,

 

I need to order a few sets of strings for my Guild F 1512E.

 

They are set up in the factory for D'Addario EXP38 - Coated Phosphor Bronze strings, "light gauge" (10,10,14,14,23,8,30,12,39,18,47,27).

 

However, I need to play in a different tuning:- 

1. The low pair E are dropped to D. 
2. The A pair are dropped to G.
3. The D high string only is dropped to A.
4. The G high string is dropped to E.

I find that the high D dropped to A is very floppy and I am wondering if a heavier gauge would be noticeably better - and if doing that, would the High G also benefit from going a bit heavier.

 

Anyone got any advice?

 

Thanks!
