They respond well to a lube tune & a custom(heavier/longer) tophat

But it actually increases power.
I would try the 37 coil xl spring. A new guide would need to be machined for best results.It should yield mid 700's with that setup. I believe the spring is intended for an R1. I got one in error & the only gun I found it would fit in was the RWS350.It's a big spring but not quit the monster the stock RWS spring is. I know of no "power" spring currently available.
Larry if you could get someone to make you a tight fitting spring guide and then use JM's tar and moly . If applied correctly I think you would see a big improvement overall. It would be easier to cock,smoother to shoot and still be at full power. Also suggest using only heavier pellets like the Crosman 10.5 Premiers.
