The HW 80 and the HW99s are both making around 11ft lb , my preferred pellet for the 80 is an eley wasp at a little over 14 grains is leaving the muzzle at just shy of 600 fps , the 99 is on wasps also at a shade over 8 grains and near to 850 fps , i zero both at 30 meters and find the .22 is acceptable between 22 and 35m without using hold over/under whilst the .177 is better at 19m to 38m..flatter shooting just means easier to operate, .177 seems to kill equally as effectively as .22 and as you said .177 has an edge on price of pellets , not as significant as your saving but about £1.50 a tin here in the UK.
