Hi Nicko, I've never used a SDM with my Loft's, after my last SDM broke way out at sea I switched to RDM's, first with Ezzy sails and now Lofts.
I have a 7.8 which might be a 2010 and a 2012 6.8 both of which are very easy to rig. I know Kel had trouble with his 2011 7.3 and SDM but I'm fairly sure he got it sorted, I'll give him a heads up re your post.
Me, mast (rdm) up the luff pocket over the cams, I don't jam it in all the way but pull the head down a little like a no cam. Then moderate down haul, boom on and out haul all the way. I then let all the down haul off, because there is tension from the out haul I pull the bottom of the sail up the mast a bit. Now wack the cams on, push down at end of batten with one hand (I think, I do it on auto without thinking) and with the other push up on the cam. Now with a RDM this is very easy they just about fall on. Then of course down haul to how you like it, I like a reasonable amount. I then set the out haul to neutral, don't go on the printed setting, Loft measure the boom from the top of the cut out to the lower leach eyelet. I make the tack strap firm, I think Choco has his tight on his race sails, play with it I guess.
Now I'm no expert and deff not sponsored but this works for me, hope it helps. I helped a SA guy last week over the phone who was having trouble and he's ok now, if you want PM me your mobile and I'll ring.
Cheers Bob.
Edit, I think and type so slow Vando's jumped me
