Default 4l60e pump questions

I have been having problems with my 4l60E burning up 3-4 clutch packs. My shift point is set at 6200 rpms on my built motor. I am going to try rebuilding it again but with a better pump spring for the higher rpms. My question to you builders is what pump should I use? I have had mixed reviews. It has a 13 vane pump which is what a lot of people have been saying is good. But as of recent more are saying the ten vane pump would be better for the higher RPM's. Opinions and explinations please? Which one should I use and for what reasons?

Anyone? 10vane or 13 vane? Just curious. Starting project next week. Trying to get things I need/want.

Thanks!

I use 13 vane pumps in all 97 and later units and do not have an issue with pump pressures.
