AGM Adventures- Update
Updated 31 Jan 17 Initial results. I will re-test the AGM after it does one deep cycle to confirm these results. EDIT completed 6 Oct Test was to put the test battery as the only battery run...

I forgot to say the reason for the test was to confirm full mosey's claim that you could get away with using one or two AGMs to supply the inverter instead of several flooded batts due to the small voltage sag under loads with AGMs. (To still stay above inverter low voltage cut off)

I was away for a while and have now read BFL13's reply above. I'll leave the below as it is in case it helps clarify or add additional data.

Wait a minute! I have posted that I used 700-800W draws on a 53lb AGM. Remember my inverter is 1000W. An AGM is defenseless against unreasonable high Amp draws from an inverter.
I have no idea what wattage draws we are talking about here.
I don't see anyone pulling C1 type draws from any FLAs; 220A from a pair of 6Vs anyone? Inverter LVD will stop that.
I don't see any basis in the Stark specs that lead me to believe it should be used for high Wattage draws. Where is the CCA spec? The Deka had a 525CCA and I did exceed that.
The telcos I have spec 800A max and 500W per cell(3000W per jar) along with duration specs. I am very comfortable with testing capacity with 700-800W draws.
Also, I have been acquiring 120V appliances that work with the 1000W inverter.
