Either the Dynamo or Optiflo would be fine for your pool. On a typical AG setup, the Dynamo will deliver around 43 GPM and the Optiflo about 48 GPM and your filter can support up to 56 GPM so there should be no problem either way. I like the pump basket lid of the Optiflo a little better, easier to get off, but either one will work fine for you.

Another option is to go with a combo unit. The PNCC0150OF2160 is a 150 sqft filter with a 1 1/2 HP Optiflo. The pump is still small enough not exceed the flow rate recommendations of the filter and you may get a better price but I would price both out to make sure.
