I see guys use either a carrot or Chinese finger traps. The carrots last a lot longer, but I don't know your experience; but if you say deal with 1.25 Dr13.5, 1.5" dr9, 2" dr13.5, ect, ect; you start needing to carry a lot of them. That really is just an issue for the guys that might do a 2" water service on Monday, a 3" gas on Tuesday, 2-2" telecoms on Wednesday and 3-1.25" telecoms on Thursday.
There is one newer fiber provider doing a larger install, and I thought it very odd, 2-1.5" and 1-1". Dealt with many that do 3-1.25, or 2-2"; but never one that mixes sizes in a single bore.
Last Thursday I watched a 160lf 8" HDPE water main; took like 4 hours to spot all the utilities, and maybe 3 hours to push out, pre-ream, push out again, and ream-pull pipe.
