Sets of Pumps

I have 3 different sets of pumps ranging from 1 3/8x8, 2x9 and 1 3/4 mushroom head cylinder.

Can I mix and match my pumps during a session or should I stick with one pump for that session then another day a different pump?

After my pumping I use Monty PE weights to keep the girth going. Before bed, I would then use Ace Bandage to prevent turtling. In the morning, when I take off the bandage I get a nice long flaccid look. I feel this is kinda counter productive where I am trying to gain girth but the ace wrap is stretching me out to give me flaccid length. Your input is needed.

Thanks

I’ve heard it can be a good idea to use the smaller one and pump up, then transfer to the big one with your new temporary gains.
