Which Atlas bi-pod for an HK91. Tall or standard?

[Celt]

I currently have a Harris HBRMS on an HK91 but thinking of moving to a Atlas. The 91 has a PTR aluminum handguard w/Magpul rails.

The question is tall or standard? Thoughts?

For bench standard works fine for me, however, when I did a long range course and we were laying prone in the grass I found the standard to be too short. It is worth noting that even when benching the rifle that my standard atlas legs were out to the first or second notch. I don't think I've ever used it with the legs fully collapsed. This was on a LMT MWS .308 AR
