Started training in Muay Thai...

[Magnum1978]

I've been training BJJ and wrestling for over 10 years with a little bit of striking here and then and MMA sparring.

Never fully dedicated myself to striking art though.

Its all hard. My body is half broken through grappling though, half the battle is managing the body nowadays but I wont stop

Interesting to hear that considering you have a background in both boxing and karate. I started off with MT and moved to boxing and found the transition much easier. You'll probably find K1 an easier transition as you don't have to deal with the clench and elbows.
