Ok, general of everything;
Vault: Both silver and bronze are handstand flat backs
Bars:Bronze and silver: Mount, cast, no angle requirement, circle element, value part, dismount. Bronze may not use high bar
Beam:Bronze and silver; minimum turn of 180(half turn), dance series, leap or jump not part of the dance series, acrobatic element that starts or finishes on beam(did not see specification, I would imagine either a handstand or cartwheel would suffice, but you can't do anything higher in bronze. Silver may allow a back walkover, since it is part of the compulsory COP, but a cartwheel is perfectly acceptable). Bronze:dismount. again, you could do the lvl 3 or 4 compulsory dismount, or FHS dismount, or round-off dismount.Generally bronze is going to want the easier dismounts, and a salto is not allowed. You could also do these for silver (lvl 3-6 compulsory dismount, side handstand to turn to dismount), or an A dismount, such as a front tuck or a brani. The salto dismount is common in silver (or what used to be intermediate). Both also have time limits of 50 seconds
Floor: Bronze-MIN 180 turn on floor, dance series, leap or jump, acro series with two or more elements(handstand forward roll to cartwheel example). Acrobatic series with backward element (cartwheel bwo, or kickover, ro backward roll example). Saltos are not allowed. Time not to exceed 1 minute
Silver-MIN 360(full) turn on floor, dance series, leap or jump separate from dance series, acro with two or more flight elements (ro bhs) and an isolated salto. Time not to exceed 1;15
NH just had their PO clinic today and rules were recently updated. These rules I just gave you are from the most recent MA prep op rule book that came out in Sept. Don't know if they will be doing a clinic and changing rules soon too. Best of luck!
