Another Pinion Angle Question

I've been reading here about setting pinion angle. The general conscious seems to be that the transmission should have a down angle of 3 degree and the pinion angle should have an angle of 3 degrees up.

Of course not a perfect world. I have a transmission down angle of 5.5 degrees. I can set the pinion angle to 5.5 degrees up. But would it be better to shim the transmission to the desired 3 degree down and the corresponding pinion angle to 3 degrees up.

BTW this is a bagged truck, the driveshaft actually goes slightly up from the transmission when at my desired ride height.

This is a LWB using a single driveshaft with RideTech StrongArm rear suspension.

Setting everything to 3 degrees might help with the driveshaft clearance problems I am having.

Opinions or suggestions?

Thanks
