Has anyone tried the Jaco or Venum vale tudo shorts? Looking at picking them up was just wondering if their worth it or are there better options available?
I haven't tried either brands. I use "True" Vale Tudo shprts. They are priced very cheap for the quality. The shorts don't ride. I use them everyday and they still look new. check out www.truefightgear.com
I fought in a pair of white jacos love um but alittle fancy for everyday training for sure... 
im using the Koral vale tudo shorts. cheap around 30$ if i remember correctly.
I have used vale tudo shorts for 95% of the time for the last couple of years.
The MMA gear 'minotauro' shorts are really good, dont know if you can get those too. Red Nose ones are good, both the long and short ones. Gameness makes solid shorts.
But the far best pair I have are the classic bad boy vale tudo shorts, you cant go wrong and the quality on those is way ahead. you can order them off their site.
I have some old Throwdowns I got on clearence. Great stuff! Looks sexy on my pudgy bod too...
