Avoidance or reduction in the duration of time in jail/prison is usually one of goals of criminal defense practice.

When you were placed on supervision your bond obligations on that case were complete so there is no bond to be revoked. If the state files a Petition to Revoke (PTR) your supervision because of the new charge, the judge in the supervision case can set a new bond on the PTR but he cannot revoke the bond on the felony case. With a pending felony, it is unclear why the supervision violation would be your "main worry." The state will elect to proceed on the felony rather than the PTR and the sentenecing range for the felony exceeds the PTR. You should retain the same attorney to handle both (assuming the PTR is even filed). Most of us provide free consultations. www.galivanlaw.net
