The PSLGT plays well at low tensions with multis so there is a little more power to be had there. I had both in my bag until I started getting a little TE and have since changed to the PK Ki5 which seems to be right in the middle between the PST and the PSLGT.
I had the Pro Kennex 5Ki and that felt a bit more hollow or tinny compared to the PSTGT. I prefer the original Pro Kennex 5G SMI version which was more solid than the 5Ki.
The only downside of the PSTGT is serving.
