Overall, I believe the quality of Victor shuttle dropped quite a bit, and very inconsistent. 1-2 yrs ago, I bought 50 tubes (same batch) of VC3. 1st box (25 tubes) seems work fine, but the 2nd box disappoint me quite a bit. The durability was terrible, due to the feather itself. Unless you can find it with a very decent price, and use them for practice or not-too-competitive games, better stay out, and go for other alternatives.
if you're in cali, your choice is a lot wider then if you're in a mid-size town in eastern canada like me. I don't know what can you get in SF. but I know in kingston, ON, Canada there is no store that would carry feathe shuttle. my side business website: www.freewebs.com/badmintonessentials
