I've been asked alot about the honey hole/411/saddle. For those that understand the system of leg lock positioning I teach you will recognize it as one of the versions of the wedge position. There are both high side and low side attacks to each position (which hip the leg being attacked is on), also there are both inside and outside side variations of each position. So for those that know the wedge the saddle is the "High Outside Wedge" (the legs are in one of the wedge configurations, hip facing outside,attacking the leg on the top hip). Its allready a part of the system I teach and has been for years. Scott Yockel actually taught the 1/4 guard entry at the first east coast training camp 3 yrs ago.
As far as transitions go. Its of my opinion ( I have nearly 21 years invested in leg locks) the Knee Knot is the superior position of control especially when its on the high inside (facing inside with the leg on the top hip), when given the option I'd choose it over the saddle.
A typical transition to the saddle from the Knee Knot is when someone is able to escape and limp out the knotted leg and switch their attacked leg to the inside lowside for me this is the best utilization of the saddle, by then switching to the outside hip transitioning to high outside wedge (the saddle, honey hole,411), making their escape attempt another attack for me. Its always been a part of the system, most of ya haven't gotten that far. Only a handle of my best leg lockers know the entire system, just like the rubber guard system its immense and should be studied in its entirety. There is a huge blue print/ mind map with all the paths, focusing on one position/path is like only learning one path in rubber guard.
