MFusion Shaft Alternative

[Frosty]

I am playing the STX #5 wood and love it! It has an MFusion 42 R shaft. I see that the MFusion is not available in 2023. I want to organise a 3-wood, can anyone tell me what shaft would perform similarly? Theoretically, this shaft should be too soft for me but I love the damned thing best ball flight I have had for years! Appreciate any advice.

I can’t find the exact spec as it’s a Japan only shaft. But it’s lightweight high launch so from that side I’d go with the Aldila ascent red as a starting point and see what you reckon?
