The wool pants are really great. Fab value for money and we found them bomb proof once they've been lanolised a couple of times.
The tie on nappies are great too. They're very soft and very adjustable; perfect for a newborn. For an older baby (from not very old, maybe a week or two actually), you will probably find that the nappy on its own isn't absorbent enough to last more than one wee/more than an hour but it's very easy to add boosters to them.
I've used them very successfully as an occasional 'back to basics' nappy when I'm feeling all earthy 
. Now, I put a Flip stay dry insert in, so basically I'm using the Disana as a way to make any insert into a fitted nappy. For a newborn, although you probably won't need boosters straight away, I would add a fleece liner to each nappy to keep baby dry.
All in all, they're both very good, organic nappies at great prices. You can't fault them really.
ETA - If it's too hard tying the nappy on an older baby, you can cut off the ties and use a nappi nippa.
