Prop question. Talon aluminum or painted SS for yamaha F115B?

[captfonsi]

Hi, maybe someone have tried this and can help me decide between the two props.
I recently purchased twin yamahas F115B that came in with painted SS 13 x 19 props.
I have read that Yamaha made the talon aluminum props especially designed for those engines since they have the SDS (shift dampener system) that fits them. Those props are 13 1/2 in diameter. I have a ventilation problem right now when in following seas and think that maybe that 1/2 inch more in diameter and the cupped blade will help me with the problem. However I will be changing a SS prop for an aluminum and would like to know what do you think of that and if someone have tried both and whats the difference in performance between them?
Those engines are installed on a SeaCraft 23 CC 2002.
Thanks in advance!!
