As I posted before, I'd go with the Ironwood wooden stock with the extra length. After the "coolness" wears out, you'll want to ditch the hollow poly stock for a good 'ol set of solid wood.

ORRRRR - you can order the IronWood set and them trade me for my current black synth set from KVAR. Holes already tapped. In fact, I'll throw in my other stock set I'm not using (full black poly set from KVAR, but the buttstock needs to tap out a screw that was stripped) and a couple of stock screws I ordered from TAPCO. So if you are handly, this would be like a two-for-one swap.
