Pro Staff 85 - stringing kevlar/poly hyrbid. thoughts?

The consensus seems to be full natty gut, or gut/poly (but even the latter seems to be not very popular in this frame).

cant be bothered getting it restrung often hence kevlar. but is it worth it
For my PS85: Tourna Quasi Gut 17 mains @50 and Tourna Big Hitter 17 crosses @48. Nice pop and good feel.

Kevlar is more lasting, yes. But remember this: you arm ain't got spare parts.
