Yeah, hopefully soon. Just been extremely busy. I haven't played pokemon myself all too much. >_<
I hope your vacation is fine. Just make sure to stop laddering once you go onto a losing streak. Make sure to take a break to relax. When you get hax'd, or you lose, it is very easy to get frusterated. If you are angry, you do not play nearly as well.
Sunny Day in my honest opinion isn't very good in a Rain/Sand metagame. Trick Room isn't very good either. Hail isn't as good as Rain/Sand, but viable.
Rain Dance is quite the team, but you probably just need to try something different with it. :<
