Testing out film

So I'm going on a trip to Venice and the Greek islands at the end of May, and I expect to take lots and lots of pictures while I am there, I'm very excited! But one thing I need to get done before then is figuring out what film stocks to take with me. I love Provia for its high contrast, rich colors, and tight grain, but every once in a while I find it's a little bit cold, and I'd like to find something a bit warmer. I'd also like to see what a lower contrast film looks like, especially on very sunny days around noon. And then there are 400 speed films to evaluate (I normally shoot 100 speed) for those times when it gets dark. To that end, I've bought:

1. Two rolls of Kodak Elite Chrome 100 (to test out the warmer palette)
2. Two rolls of Fuji Sensia 100 (to test out the lower contrast)
3. Two rolls of Fuji Sensia 400 (to test out a 400 speed film)
4. Two rolls of Fuji Velvia 100F (to give it another try)

And of course, I bought 5 rolls of Provia 100F, just because that's my standard. Hopefully over the next month I'll be able to test out all four of the above film stocks and decide exactly what combination to bring with me on my trip.
