The aerrie we are currently flying has had the same prop on since purchace 2 blade woody.We were "told"

To recon the prop is 50% cheaper but still costly than a new woody.I see some 503 have the 3-blade warps on.
My question is this?
1)Is it better to stick to 2 blade woody. "with b-box"
2)Go 3-blade warp prop?
3)Can old prop be rebalanced and is it worth it?
If we need to spend money,we'd like to do it wisely.
thanx
Woody
