Uhm NO and No. If we are going to half ass throw people and attempt to stop the appropriate place is before balance is broken. Otherwise a throw should be a throw, your attempt to slow me down and exercise control over my body prevents me from falling safely.

2. Full hand protection (I recommend hockey gloves or some other kind of "soft" protection like riot gloves. This would allow you to strike/punch, grab and manipulate people without ripping their clothes apart, cutting them with metal plates etc. It'd also let you strike unarmored areas without the likelihood of breaking a bone.
Dear God no. A) Hockey gloves are an abomination before God. B) While soft gloves may allow us to punch our friends, they do little for saving our fingers from rattan.

Basically my vision of SCA grappling would be to allow users to take their hands and grab weapons, shield, pin limbs, push and in a controlled manner bring people to the ground (Which to me would be a kill). It'd also allow some striking with the fists to the body/face etc that would not be a kill so much as part of a technique to give you time to recover your weapon/back up weapon.
No arm bars, joint locks, submissions or other UFC stuff. Because it doesn't seem likely that we'd be doing this in a padded gym with incredibly knowledgeable hand-to-hand fighters allowing stuff like that just seems like a quick way for some poor guy to get his arm broken.
So I can manipulate your joint but not lock it and somehow lead you safely to the ground (Are we doing Aikido or adding more historic European techniques?

) While I would object to locking the knee (even sport Judo doesn't do this anymore) Joint manipulations are part of the corpus of work and can be done safely, as long as we have a SOLID method of acknowledging submission.
