Hi Guys,
I'm planning to buy BFBM and NMTZ this week (30DS is starting to feel a little old and I need to shake it up a bit). Now with 30DS I just needed weights (and mat) do I need to get anything else for these other two? And if weights are involved would you recommend sticking with the same weights as I used in the 30DS or going up or down?
Thoughts?
