i don't think it is worth chasing after old eley wasps,they are hard to find and usually expensive.i have used hobby,superdome but my standard likes the humble milbro select.my webley mk3 also liked the milbros,not just the accuracy but also a much smoother shot cycle.as to power i would have thought 9 or 10flb would be reasonable to expect (no idea what my standard does) so your 8flb is not far off.they are easy to work on as has been suggested,might be worth a look inside to see what you've got.hope that helps,if not i'm sure someone will pitch in.i agree with you regarding sights i also think the trigger is good,my one is anyway. atb
