No matter what bearings you use, you really, really, really should plasti-gage them to make sure your tolerances are correct when the main caps are torqued.

Given the relatively cheap price of bearings, you can take your time and order several sizes to match up the sizes you need, checking and re-checking with plasti-gage.

In the process of building engines, crank and rod bearing sizing is one of, if not THE most critical steps you need to take. If you want to try a different brand of bearing, just take your time, and do it right. I typically measure and torque the main caps 2-3 times when guaging the bearings before finally lubing them up and leaving the lower end assembled.
