I dont think you will find S type any earlier planing than Carve and only marginally faster and then only when very well (boredering on?) overpowered.Carve will also gybe easier. (slightly)
With your 95 litre board to utilise in high winds/rough water and opt for isonic.
Dont really think you will see much benefit going to S type.
(I also think S types are significantly smaller (in volume) than quoted.)
I`ve sold my 126 but reckon its volume was more like 120 ish.
