the difference you will feel will be only in relation to the different mounting locations the 2 provide. you will not get the single plates in the same location as the sequence and the front single does not offer as much adjustment as the sequence. Mind you the rear single offers greater adjust-ability to the rear boot on a sequence IMO. If you want to use the doubles, buy the Mikro-Just and drill out the slots on the front plate.
I have both sets and prefer the sequence, going on 9 years with the same one.
