So, i found the Diablo wheel preforms best when the "Lynx" face is over the "Scythe" part of the core(the lightest part of the core), the easier way to get it in that mode is to put the Orion face over the "Quetzalcoatl" part of the core (it has a ridge going down its back, the head is the highest point on the core). Diablo Kerbecs 145WD in this alignment had a solo spin time of 3:06. Ill take some pictures to help clarify my description.
