Looking for info on how many fills are included in these various packs. Especially the rock and roll one. Any info appreciated.

Yes you can buy the Custom Pack or the XL as many times as you want,
just NOT from XLN....

I'm basically rock orientated, but I love the reggae pack too. Loads of variety as well as what I would call reggae / rock crossover. (And as an aside, It goes really well with the EZ keys reggae pack!)

I like the Metal and United Heavy ones, but that is my musical taste. I almost have them all. Got to collect them all. 

Thanks, this is great information!
