Springer HFT - Break Barrel or Underlever?

[Craig-P]

There is a springer shoot soon at the club.

Does one

1. take a nice heavy underlever to get the steady aim and subdued recoil, but pay the penalty in manoueverability and also stamina on the difficult standing shots?

2. take a lighter but more jumpy break-barrel to give the edge on standing shots and anything that needs a bit of twisted posture?

Ideally one would have built up one's strength with hundreds of hours of underlever practice but one has not.

A heavier break barrel would surely answer both briefs.
Another vote for the LGV - or a NickG 80.
