depends on the width of row your leaving,
offsetting a trailed mower more or less, wont make any difference.
i leave a 4'6" row for the baler when they dont want it raked and the 650's do tramp the sides of the row slightly, which is harder to lift when its tramped on.
but mostly id mow with the fins out flat on the ground and after turning it gets raked up so tyre size dont matter.
i only have 650's on coz the ground is so soft round here, would like 710's but wouldnt chance it for the above reason.
if the row is narrow n tall for the harvester or wagon 710's wont affect it.
