Blocks 2 and 8 were almost fully given from the start. The 25 pair in block 2 gives you the 4 in the middle there and hence, a 4 8 pair on either flank of row 8 in block 8, confining the 5 to r7c6 and lastly, the 9 in r8c5 and hence, back up in block2, an 89 pair on either flank of row 1 leaving a 347 triple in the middle row. That was a fun, but quite easy, puzzle. You just have to watch the grid at a distance to see the clear geometry, and what is great is you get it without having any number to count or hole blocking to watch for. Just like a little bird looking for its flight plan and finding the way to its nest :)
