I am planning on using a counterbalanced Burlington crank on an upcoming re build. Babbette or insert bearings ??? What is the current thinking?

If you're thinking of inserts, maybe you should consider new con rods too. The originals are getting pretty old and MANY of them are showing fatigue. Cracks around the top are not uncommon.
As for babbit or inserts, either work well but if you go for inserts, make sure you have good oil filtration.
I run a Burlington shaft with new rods, all inserted and think it is a great setup.

Simple,
Properly done babbit is a protection on your investment. Babbitt gives lots of warning if it is going to fail. As it is failling it takes a long time to really go bad. Usually the crank is not damaged. Properly done babbitt will give you 50,000 or more miles running any speed. Remember it is not the speed that kills babbitt, it is any out of balance condition. That includes timing issues.
Inserts tend to fail quick and hard. They will usually damage the block and the crank.
Properly done by an experienced shop either will do the job and last 50,000 miles.
You get to choose which you prefer.

The only issue with using babbitt is that babbitt is known for needing to be adjusted (removing shims from under the caps). My experiences is with a Burlington crankshaft, you cannot remove the rear main cap with the engine in the vehicle. Therefore to adjust the rear main clearance, you must remove the engine from the vehicle. If that means every 5,000 miles you find yourself adjusting the babbitt, then every 5,000 miles you are removing/installing the engine.

I have been able to remove the rear main cap, but it is very close.

Protect your investment and use modern insert bearings with an oil filtration system. Rod bearings have higher stresses than do crankshaft bearings, so have insert bearings put into the connecting rods too.
Also necessary is a pressure oil feed to the main bearings and connecting rod big end bearings. Splash plus mist oil lubrication is adequate for the piston pin ends of the connecting rods.
