Wadi Mujib for Non-Swimmers

Okay so it has been asked before but I'm still in denial... =( Do I really need to be a good swimmer to do the Malaqi Trail? Is that trail not any more non-swimmer friendly compared to the canyon trail? Should I expect drowning despite having a life jacket?

How about the Siq Trail? Is it true that the waters are approx 2m deep?! (T_T I am barely 5ft!) Should I be fine in the Siq Trail by myself? Or is it highly advisable that I bring someone else with me? ...(but all of my friends want to do abseiling which I also wanted except for the jumping on pools part ...should I threaten them to join me? =P )
