The only one that makes a slight difference is the Black/Cherry one, which uses a hybrid combo of solid & pearl. All the rest, available right now, are pearls. They used to have a solid one but that has been discontinued for 2 or 3 years now.

My experience was the green/yellow had a bit more length than the orangy/green but my driller thought maybe it was just the batch.  Both drilled identical, bit of difference in top weight.  Pin was identical.  Idea was 2 different surfaces.  But they kinda took care of that on their own.
