Amongst the top flight rifles there's just a difference of opinion about what is best. All have their foibles or problems, yet others run without them. The FTP 900 is a new rifle, so i'm not sure there will be much on the ground feedback, i'm not even sure it's in production yet.
The scope is down to budget... there's the falcon t50 which fits neatly within yours or you can go down the second hand route. You can down mag it for HFT use. My suggestion is try before you buy, but not think about spending £1000's because scope choice can be a personal thing, and i think it's better to buy something cheaper and learn and work with that, rather than jumping in the deep end money wise only to find out there's more to hitting targets than the kit.
