i've only had experiences with two victor rackets, sw35 and bs11. i find the sw35 wonderful to play with because it's has a head heavy balance, but not too obvious. meaning the difference of swing while holding close to the cone and that while holding close to the butt is not too big. however i have to say that victor rackets feels a bit hollow. maybe it's the vibration, but they just don't feel as solid as yonex rackets.
To figure out the pros and cons is very difficult. Generally speaking all Super Waves rackets are slower in terms of swing speed compared to Brave Sword and Meteor range.
I use the SW35 for a quite long time and it's for me a good solid racket.
Your selection is very open minded. The 30 is head heavy and mid stiff while 37 is even balance and mid-flex. These are all very different rackets.
You should know what you want.
If moderate head heavy and stiff go for the SW35. Not so stiff, go for the 36 or 30. If more even balance and midflex go for 37.
