Its been said before but its worth repeating, if your going to go up and down on a top rope on a sports climb can you use your own quickdraws/gear not the in-situ gear at the belay and then last up strips and lowers down on the insitu gear. A lot of peak district climbs (and other areas) get a lot of hammer and it just gives the insitu gear the longest life possible.
Just saw some examples yesterday and you enjoying climbing that sport route all comes from the route developers pocket or donations and volunteers re-equipping those routes, just try to preserve the metalwork as much as possible.
