I would prefer to stay on my feet in any fight, Brazilian JiuJitsu practitioners almost always resort to ground tactics and generally seem more at home on the ground.
Ahh, the old stand-up vs groundfighting debate!!
Some will say "Its always better to finish a guy standing up", while others will say "90% of fights end up on the ground, so you'd might as well focus your training there." I try and think along the lines of "90% of fights end up on the ground, but 99% start standing up. Meaning? You'd damn well better be able to do both!!!"
Right now I'm doing an art called Fudushin Bujutsu. Its primarily based on Ninjutsu, with a focus on Taijutsu (stand up unarmed combat), Koppojutsu (pressure points and bone breaking), and Jiujutsu (groundfighting and takedowns). It also draws influence from Muay Thai, American Kickboxing, Aikido, Tae Kwon Do, and Military Unarmed Combat.
I'm also doing another style of martial arts, that doesn't really have a name. I guess the best way to describe it would be self defence training, and training for mixed martial arts (UFC style) tournaments. We're learning JiuJutsu, Kickboxing (Muay Thai, Savate, American), wrestling, and Military Unarmed Combat, among others. At first I was skeptical, but now I think that the fact that this training doesn't limit itself to any specific style is a major bonus on the street. Its just a mix of what works in the street and in the ring.
Both these clubs are withing walking distance of any living in pers at CFB Petawawa, so PM me if you're interested and I can give you times or even introduce you to the instructors. The members come from all units around the base, plus civvies so you might just run into someone you know.
