DIFFERENTIATE BETWEEN WAZARI AND IPPON???
Answers
Answer:
Actually, the two are so closely related that until 1997, Ippon Seoi was not recognized as a distinct shoulder throw of its own, only a variation (there are lots of them, some in which you don't have to turn your back on uke completely to put it on) of same.
In theory, you are correct about the control issue, that with the hand gripping the uwagi, and the forearm up in the armpit, you do maintain more comtrol. This is fine theory if one is to use this shoulder throw in randori no kata, or other kata (remember that ippon seoi is done off a straight punch in nage no kata).
The problem is that it takes more time to put on an effective morote seoinage in shiai than it does for ipppon seoi nage, but one can overcome this by actually releasing the dogi once your arm has reached its target.
Even today, most do not distinguish the two as different throws when observing the winning throw. They are all seoinage.
If you believe morote seoinage is more comfortable and a stronger technique for you, then certainly, use what feels right, but always practice throws in which you may find yourself in position to utilize. Sometimes, you can attempt ippon seoinage, then drop to the knee or knees and do ippon seoi otoshi from either side. Certainly you can utilize seoi otoshi as well, but in this situation it does limit you into doing it on one side when ippon seoi otoshi can be done by grasping either arm and pulling down from either side.
On a personal note, I found that ippon seoinage to be faster, so there are advantages in both, but it isn't wrong to favor one over the other. I did, but I sill used morote seoi when it presented itself. Different times, different rules, distinct advantages or disadvantages, but yes, you should be able to so both equally well in spirited randori.
Neither will hurt the other, but you may simply be adding another favored throw to those which you favor. Also, against a much, much taller opponent, I've found morote seoinage to be favorable, and with an opponent only a few inches taller, the ippon seoinange is more compelling.
