Get out and start training!
The only problem I have with sparring is I can't go full bore, so I find myself "handicapped". I did have one friend who would full on fight with me, but that's rare. The train how you fight/fight how you train issue arises. A while back this was found with most police who died in firefights, they were instinctively pocketing spent shells from their revolvers instead of immediately clearing the cylinder & inserting fresh ammo. Once that was finally discovered, the practice stopped in most department ranges. Unfortunately most don't learn the hard lessons of what works/what doesn't in youth anymore, but no holds barred fights were the best training I could get. One thing I love is when you see a punch coming, it's that much easier to use gravity then do some face/neck stepping. That's the point after all, finish the fight as quickly as possible then move on to either the next threat or get out of there before you hear sirens. Regardless of experience, stay armed & develop muscle memory in employing your weapon(s). Never know when the scales may be thumbed from what you can handle physically to a gang of mongrels. As little as 10 years ago merely deploying the weapon was enough to dissuade an enemy but with today's idiots they have no sense of self-preservation so a show of force is often needed to send that mental lightning bolt of "oh shit, I better run".
No krav maga needed.
