Tons of good options. Dream options would be an OS 25XZ or Novarossi Roma , or for a bit less dough but still big power, an Alpha A352 .23, or even the Alpha A852.. OS or Picco 28 with +2 on the CB would be cool too.. I even like the relaly cheap .28's from SH like the Losi 454/LRP Spec 3, and the Dynamite Big Red .28. There are tons of options. Depends on your priorities, budget, what exactly you're looking to do, etc..
