I've had a few posts regarding the Toyo Versado LX's that I put on my LS last year (V rated 245/45-18) - about 20,000 miles ago, and still love these tires. Very quiet still, great handling and performance (I'm a bit older now & more settled in my driving style, and I don't pretend that my LS is a Porshe) and appear to have plenty of tread left - I use a set of dedicated snow tires here in Minnesota, so at least a couple more years left on this set.
They are available in H or V ratings, with the advantages/disadvantages that you are already aware of.
Anyway, just throwing another manufacturer out there for your consideration.
Let us know what you decide!
