Being a turtle you need to have strong income from mines, so it is best to cluster your planets all close together and build some high level mines on them.
Choose one of your planet to build a good shell on. I would say a good shell composotion is:
10k Light Lasers to every 500 Ion Cannons.
500 Ion Cannons to every 50 Gauss Cannons.
50 Gauss Cannons to every 25 Plasma Cannons.
So a set up would look like these:
10000 LL
500 IC
50 GC
25 PC
Or
25000 LL
1250 IC
125 GC
62 PC
Some people also go for a heavier Plasma Cannon build where you forget about the Gauss Cannons and Triple/Quadruple the Plasma Cannon coeffiecient.
I hope this helps you and good luck turtling.

Don\\\'t hesitate to ask more questions.
