I've had a few pcp's in the past,as already mentioned above the AA400 series (got one now with tench reg) faultless and lazer accurate,the webley fx2000 I had in .22 was stupidly accurate and very consistent and an absolute doddle to replace the seals....would love to get one in .177 carbine,rapid mk1 provided it hasn't had the shed treatment by Mr club hands while wearing a blindfold,again an easy gun to work on.
Had a hw100 that kept springing a slow leak but was very accurate but heavy,also had the daystate huntsman in both calibres...got to be the best looking and very nice handling pcp but I found every now and then it would throw a flyer.
