In fighting, be it judo, jiu-jitsu, or any other form, it's not about what you want. It's about taking what the opponent gives you. You named two techniques that worked well. You were taking what the opponent was giving you. The key is to continue doing it until the opponent attempts a new tactic. If it works, why change it? That said, in this situation it's important to circle. Circle one way, then the other. You're looking for the point where your opponent stops moving with you. That's the chance to enter. From that point I pummel up to an over the shoulder or high collar grip and turn. Because the opponent is off balance forward (into you) you can easily pull him onto your hip for koshi garuma, o goshi, uchi mata, tai otoshi, seio nage or any other forward throw. The key is that your opponent will have to react to stop it. Then you do a rear throw such as o soto gari and ko soto gari. You could also drop as you turn and do a double or single leg (illegal in judo comps). Good advice. The circling idea sounds good. Didn't even think of that. Was so focused on getting the throw rather than taking what he gives me and working him a little so I wont have to try as hard.
