at least one titanium, if not two
let's says...
1. Easton STI2 Typhoon II (although if this bat doesn't count cause it wasn't really produced, i'll take the Louisville Slugger TPS Titanium
2. Miken Ultra Maxload
3. RD28 utrip (#0001, 1000, or 0011 would be ideal)
4. RD28 asa (#0001, 3000, or 0011)
not sure about my last pick, but I wouldn't turn away something like the zapper or tidal wave.
there's plenty of other bats I think would be cool to have, but I already have them, so it's hard for me to put them on a 'wish' list.
