Hybrid question for Fischer vacuum pro 90

#1
Hi guys,

I have half set strings. They are Babolat VS Touch 1.30mm and Ashaway Kevlar 1.10mm.

Should I put Touch at mains but according to people here, it should be crosses instead?

I will use low tension. Is Kevlar should be around 40lbs to prevent future arm problem?

Please advise.

TIA
