Thanks Simon - yes this isn’t getting any easier as LB have flat out told me not to use the AR25 even when I explained it has been done before.
You make excellent points - as the aero aspect of the WG44 is for me its least useful point.
- The AR25 is not strong enough for a unicycle.
2. If you want an asymmetric rim, what about the XC925 MTB rim? The XC925 is a hookless pro rim, and the max tire pressure is 40psi. I recommend the enhanced version weight 440g+/-15.
3. The road disc rim is also available. The symmetric rim has better aero. Such as WR40 and WG44 rim. I recommend the WR40 enhanced version weight 520g+/-15 and WG44 enhanced version weight 530g+/-15.
I guess I want it to be different enough from my AM935 to make it make sense of recycling my 32h from my Braus G36er. Really first world problems here… but I can’t get that Green and Orange Touring P-frame G-700c out of my mind 
I kind of feel wedded to the hybrid hooks and 700c even though narrow 29er rims are in terms of tyres are the same compatibility wise.
Going with their enhanced WG44 would make for a heavier rim than my AM935 which seems crazy. I wonder if LB are just worried about people breaking their rims in unicycle duty now they’re making a unicycle 36” rims ….
