[NRVR-Members] What are folks doing for buying new motor casing hardware now days?

[Thomas Tweeks Weeks]

Thanks for the useful info Jordan. I hadn't dug that far into all my options yet, but was just starting to weed through the motor selections to lift this big 32lb rocket for my L3 cert flight at LDRS. I was looking at a small M, 75mm single use.
 
Initially I was thinking that I wouldn't use 75mm size motors that often back here in Blacksburg, and would just mainly fly on a 54mm adapter.  However, at 32lbs it seems that not that much in 54mm will do the job on this bird (5:1 thrust requires an avg of 720N thrust, unless looking at VMax or white thunder).. so it's looking like 75mm is the most useful size motor for this thing.
 
Maybe 75mm CTI hardware will work just fine.
 
Comments or related thoughts welcome.

CTI Hardware for 75mm was built specifically to fly Aero tech reloads. It was developed for the (military/scientific?) community when AT had their production stoppage. There are physical differences - I presume to circumvent patents - which requires an additional o-ring of standard size, avail at Amazon for under $1 each in qty 5. But there is no functional difference. 
I decided to skip 54mm HW and just fly big 38s with an adapter. (tho I have CTI HW, so who knows what will come of that)

Hey all..
 
So I'm in the market for 54 and 75mm motor hardware for my new big bird.. and am just wondering.. is anyone buying Cesaroni any more? I really like Cesaroni since they first came out with the ProX line. I mean Aerotech is okay.. but they sure are messy (compared to the Aerotech 54mm anyway).
 
But I was thinking about just doing my L3 on a single use small M Aerotech.. and continue using single use 54/75mm until the news is in on Cesaroni..
 
Thoughts?
