Considering the BA Copper Spur UL2 even thought it's a little heavier than the Fly Creek just so I have a little more room to sit up, change clothes etc.
Your MH tent has 2" more headroom and 2 sq ft more floor area which would be nice, but at a penalty of 2 lbs 8 oz packed weight. You got a deal on it though so that certainly is a benefit. The BA CS2 can also be run as foot print and fly for lighter weight. I'm best price I'm seeing the CS2 for around $339ish. I'm waiting for a smoking deal on one somewhere.
Sorry I don't have any direct or indirect experience with your MH tent. Just giving you a comparison. Looks like it will allow you a comfortable stay albeit slightly heavy or give you a lightweight option with the fly only.
