Avoid 48x16 if you plan on skidding- with only one skid patch it will really eat up your tire. I was running 48x16 and really liked it so I switched to a 47t chainring which is only 2% different than running a 48t. I get 16 skid patches now and I can't notice a difference.
I'd suggest 48x17. you'll be able to go fast but also be able to manage hills just fine.
