Graceless

I'm a newbie slotting out my first 50, who happens to be a Bio/TW tanker, and given that I solo pretty often I love the idea of using procs to enhance my DPS, but Mids is super intimidating as somebody who never played the original CoH. I'm using the build you outlined for SR/TW as a rough guideline, but given that I don't have the inherent +Recharge that SR offers, what attack chain should I be shooting for and how much global recharge do I need to stack to get there?
