Alex DX32 Rim or Monty rim for trials

I am interested in getting a trials wheel set. sells the trials wheel set either with the Monty rim or the Alex rim.

I don’t mind paying the extra 25 bucks for the alex rim if it is worth it.

Is the Alex rim lighter?

Is it as strong or stronger?

Is it easier to mount tires on it?

Any reports of tire slippage as has been reported lately with some of the MOnty rims/ tires?

Any drawbacks to the Alex rim?
