I've never noticed CA in the SE and cant say I ever really have in the Opticron either, though I've never gone out of my way to look for it. Though I certainly notice it when its there in binos and scopes, most recently in an old Kowa ts 611 scope and zoom that was almost psychedelic with it.
You're right the Opticron/Minox are crazy good value, way better in my experience than all the chinese ED stuff. In fact if I was mainly into coastal or fairly open habitat birding the HR WP would be my choice over the SE regardless of price.
Really, anyone who doesn't want to fork out for an SE and wants to see what all the fuss is about regarding the legendary view of the SE just get an HRWP instead, the overall view of both is of exactly the same washed clean, transparent pin sharp quality that I certainly never saw in either my Hawke ED 8x43 or my Zen ED2 7 x36.
Interestingly the only roofs I've tried that gave me that feeling were the EDG II 8x32 and the SV 8.5x42 I recently tested out, ( this was just in the street outside a bino shop though so maybe not a very good test ) I thought the FL 8x32 I also tested was clearly really poor in comparison.
