Default VF37 Twinscroll - billet compressor wheel upgrade - 11 blades vs Dual 6 blades

I'm thinking of upgrading my twinscroll VF37 with a billet compressor wheel (30% lighter, 49.6 mm / 61.98 mm (Inducer / Exducer)).

I have two options: 11 blade design or dual 6 blade design.

What would be the pros / cons for each one (spool, top end, middle torque)?

I've done it on mine - not sure where the 30% lighter comes from I think it was more like 4 - 6 grams

I went for the GTX style 11 blade version

cons have to get the cover machined as its a bit bigger than stock + you then need to balance the CHRA

pros pulls hard to redline
