no they aren't fully rounded,there's a flat side,but it doesn't seem to make any difference to the fish.yah they pretty much are a version of beatle spin bodies,but not exactly the same.i like to just throw em on an aberdeen style long shank hook without weight mostly.i don't have any jigheads that would fit them.probly need something with a long hook.would be awesome to have 1/64s with long enough shank hooks.and i presume you are talking about the longer 1.25" ones?the smaller 1" ones i can fit on 1/64 heads i got.just need to clip the tip of the bait body a little.anyways today i went to hospital for chemo and a scan.i go to childrens clinic because im dealin with a childhood cancer even tho im 29.anyways i found the perfect colored bright orange crayon and brought it home with me for another small batch of the correct orange color i want :D!
