Hi Noel, and welcome to the fig forum...I have found out over the years that the cuttings that grow the most vigorously, and seem to have the most energy stored in them, are the ones that I cut off further down the branch(closer to where the branch meets the trunk)...I think the method of rooting may limit some growers in the choice of the cuttings that they use...in my case I am somewhat limited in the size due to that fact that I root my cuttings during the tail end of the winter months, and use an indoor rooting method that uses a humidity dome that is 7" high, also the growing plugs that they are placed in will only allow the thinner cuttings(maybe 3/8" before they break the rooting plug)...on occasion I do take the larger cuttings that are available, and use a different method to root them, but for my year to year rooting I prefer using the smaller cuttings...it simply comes down to a matter of choice.
