Diana Which Altaros regulator for Diana Stormrider?

Hello everyone!

I just bought my first PCP, a Diana Storm Rider in .22.

I would like to add an Altaros regulator but am at a loss as to which foot pound level I should order.

I am looking to get a good consistency of shots, in the 800 ft per second range with an average pellet weight. I will mainly be plinking in the backyard.

On their website, Altaros has options from 5.5 foot pounds all the way up to 44 plus. I live in the US and do not have any regulations on power levels.

Any suggestions on what I should order based on my user requirement?

Thanks so much in advance, I am really enjoying this new sport and this wonderful forum.
