Just got Toyo Proxes FZ4--should I keep them??

It is getting warm here in New England, so I had to get new tires to replace my Bridgestone Blizzaks. Anyway I went to the local Town Fair Tire and was able to get 4 Proxes FZ4s (V rated) for only $90 each with I found very reasonable. They basically told me these were some of the best tires there (and I think they actually undercharged me accidently.....oh well??). My dilema is that I just read a bad review of the tires online complaining in large part that these tires can't handle rain and hydoplane. I just drove in the rain and had no problems to speak of......granted, I wasn't driving very fast.

Do you SVXers have any opion/experience with these tires? I do have 30 days to return them no questions asked. They look great, but safety comes first. I really do appreciate it!
