Hi aspad,
Yes indeed, you can put your 1200 Tobinators on the Secdem with no problems at all. Same fitment as on the standard screen.
I found that the Secdem screen resulted in better wind protection but there was a curious thrumming noise at motorway speeds which I tuned out when I fitted the Tobinators to raise the front of the screen a tadge.
I found the Secdem to be pretty poor in the completely upright position due to the upward "kick" in the screen profile. It definitely works best leant back, but you lose height and therefore wind protection that way, but you can use your Tobs to regain that height whilst still keeping it leant back.
I went back to the standard screen as I wasn't overly keen on the looks of the Secdem.
Cheers
Andy
