Selecting bulbs to chip, guidance

All,

I plan on chipping bulbs this season and understand that single nosed, round bulbs are what to use. However there are some varieties where the only single-nose bulbs are newly separated off-sets that are definitely *not* round. But, they don’t show any signs of dividing. Do these types of bulbs have lower success rates? My concern is a few varieties are so prone to divide that if I leave these off-sets for a year to fatten up and get round, they’ll start the division process. Any words of wisdom MUCH appreciated.
